Checkboxes across a Scene

Hello,

My team is using Storyline360 as an assessment tool for EMS continuing education and I'm running into an issue with my design I hope we can solve.

We're creating scenarios for learners to test out their knowledge at the end of the course, and one of the ideas I would like to incorporate into the scenario is a checklist to be used as a user guide. It would be as if they had a clipboard with them during the exercise and as they complete certain tasks they can check it off. It's a tool purely for the user to keep track of their actions and not in any way part of the back-end assessment. I built the checklist as a slide layer that can be activated by hitting the icon in the bottom right corner, and closed by hitting the X that appears. This was templated in so every new slide can have this feature built into it. Alas, I just realized my mistake. The checklist resets with each new slide and isn't carried over as the narrative progresses. This completely undermines the utility of the tool. 

Is there a way to have a checklist that exists across the whole scenario and not a separate instance for each slide?

Thanks!
