  The approach I'd use is as follows.
  
  Create an array that has the current zone controlled for each touch panel.
  
  So, if there are 5 TPs, the the array Current_Audio_Zone would be 5 cells wide. (one for each TP.)
  

  DEFINE_VARIABLE
  
  volatile dev Audio_TPs[]=
  {
  dv_TP_01
  ,dv_TP_02
  ,dv_TP_03
  ,dv_TP_04
  ,dv_TP_05
  }
  

  
  The client selects the zone they wish to control which sets the array Current_Audio_Zone [this TP] to whichever output they selected.
  

  DEFINE_VARIALBE
  
  volatile integer Current_Audio_Zone[5] // number of TPs.
  volatile integer Audio_Zone_Buttons[]=
  {11,12,13,14,15,16,17,18}
  
  DEFINE_EVENT
  
  button_event[Audio_TPs,Audio_Zone_Buttons]
  {
  push:
    {
    Current_Audio_Zone[get_last(Audio_TPs)]=get_last(Audio_Zone_Buttons)
    // now we know which audio output zone this TP is controlling.
    // do something...
    }
  }
  
  

  
  Then when they selected a source for that zone, I'd populate a Current_Source[number of output zones] with that source.
  

  DEFINE_VARIABLE
  
  volatile integer Current_Source[8] // current input selected for the 8 outupts.
  volatile integer Source_Buttons[]=
  {21,22,23,24,25,26,27,28}
  
  DEFINE_EVENT
  
  button_event[Audio_TPs,Source_Buttons]
  {
  push:
    {
     
    Current_Source[Current_Audio_Zone[get_last(Audio_TPs)]]=get_last(Source_Buttons)
    // now we know which source is selected for the zone being controlled by this TP
    // do something...
    }
  }
  
  
  

  
  Of course, I'm oversimplifying this for the example but this is the basis for it. I'd then create a function to handle the actual switching of the HA switcher and another hink of code to deal with all the popup page navigation and so forth.
  
  Hope that helps.

  I'll try and wrap my head around that. Cheers~!

  I like to use structures for these situations, and I load the relevant data into the structures. Basically I'll have a structure that tracks each room's information (current source playing, current volume in that room, name of the source in that room), and I'll have another structure that tracks the panel's information. The button events will store the selections from the panel into the PanelInfo structure until it's time to execute the switch. In other words, client will choose a room or rooms, then the desired volume, then the source. Once they've made all selections, the switch is executed and the volume, and i/o are sent. The data is then parsed and that information gets stored in the room info structure and relevant data is updated on the panel for feedback. This works well because there's always the possibility that one person will be manipulating one zone while another will be manipulating a different or perhaps the same zone. All of the selections each person makes are stored independently with their own panel until the switch is executed.
  
  Also, it lowers the amount of traffic sent back and forth to each panel since the data is only updated or refreshed on panels that are on the matrix or wholehouse pages, and they can call it out of the stored data.
  
  The way I implement it in code is probably overly complex, but it works well for me, is simple for the end user to execute, and system response is very snappy. I use lots of GET_LASTs, and BUTTON.INPUT.DEVICEs, and just simple IF/THEN statements to figure out what to do.
  
  Here's an example of the structure definitions

  DEFINE_TYPE
  
  STRUCTURE _sPanelInfo
  {
     INTEGER nCurrentSource                       // DSS units 1-12, DVDs 13-20, Tuner 21, CD 22, iPod 23, 24 is unused  
     CHAR    cCurrentSource[25]                   // Descriptive name of source
     CHAR    cOutput[135]                         // Up to 48 Outputs (digits + the space)
     CHAR    cInput[2]                            // Up to 99 Inputs (2-digits total)
     CHAR    cVolAbsolute[4]                      // Volume Absolute String (VA) (-700 to 100)
     INTEGER nWholehouseRoomSelected              // Which Room is selected on this panel 
  }
  STRUCTURE _sRoomInfo
  {
     INTEGER   nCurrentSource
     SINTEGER  nCurrentVolume
     CHAR      cCurrentSourceName[30]
  }
  
  DEFINE_VARIABLE
  _sPanelInfo    _PanelInfo[16]       // All 16 panels have access to multi-zone
  _sRoomInfo     _RoomInfo[48]        // Track data for each of the 48 rooms
