Importing scenes with existing variable - SL2
I want to import a scene that consists of a series of multiple choice questions and a results slide. When I go through the normal import procedure I get a window which says I already have results variables. (I already have a separate set of questions with their related results slide. I want both, kept separately.) The window offers me two options - merge the two sets of results, or rename the imported variable. That's great, except that only the first option is 'live' and it's the second option I want. How do I make the second option available so that it is selectable?
