Customized learning path based on user selection

Hello Storyline community!

I've been trying to wrap my head around about a customizable learning path for learners based on their selection.  Here is a gist of what I am trying to accomplish:  A learner selects up to 14 topics on a page and depending on their selection they are presented with the slide of the topic they selected. For example, if a learner selects topics: 1,5,8,9, and 13, then they could navigate only those slides and skip the rest. The other element is to have a standard intro and conclusion for all.  Basically the customizable path for the learner is in the body of the course. 

Any suggestions or ideas about the build? Thank you so much for any insight!

Cheers,

J
