Changing root on multiple tracks at once

Has anyone figured out a way to change the key(root) of Waves Tune Real Time on multiple tracks at once? We use it on all of our vocalists and it’s a hassle to have to open each instance of the plugin on each track, to be able to change the key for the next song. This is happening live, so don’t suggest a snapshot or midi note control or automation of some kind. This is in a DAW used for broadcasting live stream.

I am having the same question. It would be nice to have a master input that you could change once and that would populate the individual channels. I added the plug in to the vocal group, but only did work when the lead was out front and clear. Otherwise it could not decide which pitch to correct. We are a group of volunteers and 5 vocalists to change between every song is a stretch.
