FREEZE Frame

Would it be possible to implement a master override slide or button 'Freeze Frame' so we can edit the schedule while LIVE without showing the slide editing on screen?

Presenter runs on your primary monitor, while the display/output is on extended desktop / separate video output. You can always make changes and edits on your primary screen without needing to freeze anything.

Maybe I'm projecting onto Columbus's original request, but, in my experience, of course Presenter runs on a secondary display, but there are actions such as switching into another song/presentation that will impact what's displayed on screen. I was stuck last Sunday needing to Sync Changes from a Google Slides presentation that I was told about during the service, and couldn't freeze the output and hit Sync Changes without impacting what was on the screen.
