Rise 360 Quiz

I created  a quiz called "Wastewater Systems Quiz".  I export to my LMS and do tracking using quiz result and set it at reporting "passed/incomplete".  When an employee goes into the LMS and takes the quiz they need to keep proceeding through to the end and they pass or fail.  Is there a way to make this, where they can mark an answer or skip an answer and save and come back to finish it?  We want this as an open book quiz and not pass or fail right away! Please advise!
