Because there is no feature to ensure the user has clicked all relative elements or hotspots on screen (hopefully yet), I am using branching. It would be very useful to be able to duplicate a page, all its elements, and timing of those elements to a branching page rather than copying and pasting each item and then retiming it.
You can use Existing Pages when you add to your branching scheme; this would enable you to duplicate a page without having to re-create it.
