With all of the attention to New Quizzes, I wish you would also consider having the option of advancing quizzes stimulus by stimulus and not just by question by question. This would mean any given stimulus and ALL associated questions for that stimulus only would appear.

In New Quiz Settings, teachers have the opportunity to advance the quiz one question at a time. However, oftentimes teachers will use a Stimulus and then multiple questions for that one stimulus. Additional functionality should be created to allow teachers to advance the quiz one stimulus section at a time. 

This clustering improvement would also lend itself well to having the stimulus & associated questions in the item bank having a permanent association with one another.  For more information on that idea, please refer to this Idea Conversation.
