I'm working on a Python Add-In in which I'd like to have a button that opens the 'Change Layout' dialog window (see screenshot). I've been poking around and haven't been able to come up with any code that will do this. I tried simply dragging the button into a menu in the add-in, which works locally, but doesn't seem to stick when I copy Normal.mxt over for other users. Anyone know if it's possible to open this dialog window via python? Any feedback is appreciated!
