Require user to scroll to bottom on longer questions -- Storyline 2

I've been searching for a way to require users to scroll all the way down on longer questions in my quiz.  I had the ability to do this in Quizmaker '09.

So far, I haven't found that option in Storyline 2, and I've perused the forums hoping someone else had the same issue - however, no luck I've not found anyone asking for this.  I was not able to locate this feature in the tutorials.

Is there a way to add this setting to my quiz in Storyline 2?

Thank you!
