How to make some lessons mandatory in Rise 360?

Hi E-Learning Heroes,

I would like to make some lessons mandatory and some optional in Rise360; the "Importance & Accountability" section for instance, mandatory for all users. 

If I use the Complete All Blocks for the mandatory lessons can learners still skip forward past the mandatory lessons in the Menu? I want to leave the side bar for quick review navigation when I remind them to review material they have questions about in the Summary section.

I see that the sections after the "Quiz" are greyed out in the sidebar Menu but when I use the "Complete All Blocks" Continue button at the end of the lesson(s) I need to make mandatory, other sections below it are NOT greyed out in the sidebar Menu.

All help is appreciated, thank you!
