I’m not sure if this has been discussed, but is it possible to copy and paste frames between Master Pages in the Master Page Editor? It does not seem to work for me. This would be a big time saver. Or should I be taking an existing Master Page and make individual overrides manually?
EDIT - Nevermind. I figured out that I just need to base the new Master Page on an existing Master Page and make changes to this copy, rather than try and copy all or some of the frames.
