I'm producing a show and using my Blue Yeti USB mic as a Talkback mic to speak to different guests privately and individually during the show. Some of the guests are coming in via vMix Call (video callers) and some are coming in via Zoom (phone callers).

I know to use the VideoCallAudioSource shortcut to quickly and efficiently change the audio source that my Vmix Callers are hearing (e.g. from "Master" when I want them to hear the program output, to "Bus B" when I want them to hear from only me/my microphone). When I set up a VideoCallAudioSource shortcut for the vMix Call participant's audio to be changed to Bus B, is there a way for me to also have that shortcut simultaneously change which bus my Blue Yeti microphone broadcasts to (e.g. from "Master" to "Bus B" only), or do I need to change that manually in the audio mixer?
