I tested this just now for you and it works fine. Start recording a new CC and then make the Multiviewer changes as desired. I did it all through Dashboard because it's so much easier there. Stop recording and you'll have a CC that does those changes automatically.
You could also do it through RossTalk, I use these two commands sometimes:
- LOADSET [setname] - this configuration could have the multiviewers set up to be the way you want, including source mnemonic names
- MVBOX [multiviewer number]:[box number]:[source] - To change a box's source on the fly. Combine this with the MNEM command to rename the source (MNEM [source]:[new name]) and you can have the name on the box update as well (assuming you have the multiviewer configured to show the label)
Hope this helps!
