Is there a way to copy a stack and give the copied stack a new name
I have written an outline for a film: There are many changes, including some additional scenes and locations. Is there a simple way to copy an entire stack (duplicate it) and give the copy a new name, like 2nd Draft. I can't see any way to do it. Save as gives me choices, but not to create an identical stack which could then be revised and edited. 80% of the story remains the same but I don't just want to delete and edit the current stack, but rather a clone. It seems like something obviously missing, or am I missing something.
