Accessible drag and drop quiz and the results

Hi, 

I asked this question here - Build an Accessible Drag and Drop Interaction in Storyline | Articulate - Community, but I don't think it's being monitored (Or I did it wrong😄). 

I followed the instructions given to create an accessible drag and drop quiz interaction, and it works for the most part. The challenge I have now is for the results of the interaction to be included in a results slide along with other quiz questions that have used the built-in layouts. 

I've had a go at custom variables to track the interaction results and I can see that score on a result slide. 

I can see someone else on the original discussion page also had a similar query. That being, can this type of interaction's score be included in an overall quiz results?

Thank you

Karen
