Can Course Navigation (left nav bar in a course) be set (and locked down) at the Admin level? I see that in the Course Settings, Course Navigation can be edited. But I want to know if an admin can override this. Can it be done in Canvas "out of the box" or does it require scripting? 

Does anyone have experience with their institution "locking down" the course navigation? Does it work for you? Why or why not?

Thank you.
