Hi Sherry,
There is a way to dynamically change what questions are presented to the learners and this way achieve what you want.
I would have 2 question banks, and 1 result slide.
When learners choose which role they have, 1, 2 or both, this selection would change number variable eg. Assessment to 1,2 or 3. And then playing with triggers to jump to specific slide (draw from question bank 1, draw from question bank 2, or both).
Important thing is to tick option to mark only presented questions.
If you have a file I could help you setting this up.
