The platform definitely lacks this small feature: Admins and Instructor have to be able to change the progress for a Learner manually.

Now the only way for an Instructor to change the progress instead of a Learner is to Log in as this user and complete all the sections for them, one by one. It's very time consuming, especially with the forced video watching or multiple glitchy checkboxes!

Hiding lessons for the Learners is not an option.
