Is there no way to attach questions to a stimulus and pull them from a question bank with the attached questions?

I need to create a quiz that randomly pulls questions from a question bank so that each student has a slightly different assessment.

I tried to create stimulus questions that each had three questions asked per stimulus item. When I pull the questions from the bank it only pulls the stimulus and not the questions. This prevents me from using question banks to help randomize questions in the assessment. 

I was hoping to create multiple questions like this and pull them randomly from a question bank:

Has anyone found another creative option for this?

Thanks for any help.
