Softkey/Talkback External Control

Would love to see talkback on/off able to be controlled through MIDI on the Avantis. Or, even better, be able to control any softkeys via MIDI.

Use case is in a double Avantis setup, trying to have a talkback mic at both desks that can communicate with the band, and would be awesome to be able to sum them together and bring them into the talkback input at FOH (where monitors come from) then be able to toggle the talkback on or off from either broadcast or FOH.

Obviously the current workaround is trigger scenes for assigning and un-assigning the second mic to IEM channels, but would be nice to streamline that and not have it risked getting screwed up by other scenes.
