I want to set up a talkback feature which would allow me to speak to people on every audio Bus with a Stream Deck button press, then return everyone to their original audio Bus when the button is released.
For example: I have a presenter on the Master Bus on a "main stage". I also have 4 callers in a "green room" chatting away to each other on Bus A as they wait to go live.
I put out a call to everyone, temporarily changing VideoCallAudioSource to my talkback channel, Bus G.
At the moment, on button release, everyone has to go back to either Master or Bus A - there is no way to distinguish between them. With a toggle command the presenter and guests could all be returned to their previous audio Bus.
