dual IR emitters

has anyone added a second IR emitter to an NI-700 turns out I am one port short. I was thinking of custom capturing all of the IR to one file and just connecting a second blink emitter to the port to allow for control of two devices.
I used 4 IR devices on 1 port but i needed an IR extender. Its no problem for 2 devices we ive done it before.
I'm told that if you wire the two IR flashers in parallel, you run a risk that any given pulse will be grabbed by whichever LED switches fastest and the other LED then won't flash.
So wire them in series - making sure you get the polarity right.
I hate doing this though. It requires you have a custom IR for whatever the combination happens to be, and this offends my sense of reusability.
