With the latest update (thank you) functionality has been added to the VCA (thanks!).
I do however think it would be better and more logical to change what “mute” does on the VCA:
The other buttons change the state of the channels the VCA controls. Press “solo” and they solo, “record” and they go into record mode etc, so it would be logical and consistent that “mute” mutes the channels the VCA controls.
Also, it seems to me that “mute” does nothing more than what turning “read” off already does. So there’s really no need for “mute” if we can just as well just turn off automation read.
I would also argue that the nomenclature would be more consistent if “mute” refers to audio as it does everywhere else, and “read/write” refers to automation.
