Learning Interaction variables

I am trying to create a slide that has a multiple answer question and a multiple choice question on the same slide. I know I cannot do this with any of the default Quiz slides, but I am thinking there might be a way to make it happen with Learning Interactions. I've inserted a Radio button interaction and a Checkbox interaction on the slide, and I've added variables for each one. The answers to these interactions will decide where in the course the learner goes, so I want to be able to recall those variables later. However, they don't show up in the Variable editor window. Is there a way for me to assign the values of these variables and recall them later? If not, is there a way for me to have two questions on one slide without having to go through the complicated process of creating custom questions with advanced actions and variables?
