Unrestrict Access after passing Course Opt-Out Assessment

Hi Tom, I tried this. The course is lengthy and the customer does not like how long it takes and how it looks cycling through when it "un-restricts" all of the pages/slides.

Is there a way to set a trigger or variable that when the learner passes the opt-out assessment with the passing score that the trigger will tell the pages/slides in the menu to unlock? I feel like there is but I'm stumped as to how to do this. 

Thanks for all of your help! I appreciate it :-)
