How to Chunk a Loooong Rise Course

Hi Everyone, 

Question...we do an Annual Education push for all our staff; and as it contains the yearly compliance courses, etc., it is a very long course.  We have already broken it into chunks using Rise, but it still runs as one long course.  

The issue we are having is in our LMS - which has never been known to do bookmarks right when users need to stop and start.  And users are finding when they need to leave the course and then return, they need to go thru the entire course again, as the LMS didn't bookmark.  In addition, the course has just one place where it has users branch off based on their job titles.  

Our LMS will let us know larger courses (we use Oracle, so they're called Specializations) where several courses make up the Specialization, but again, with that branching scenario, it makes it touch to create separate courses to fit neatly into a Specialization.  

Anyone else do courses that branch and would otherwise be very long if you didn't use the approach you've learned to use?  If so, can you share?  Thanks so much!
