Ability to LOCK course lessons after a certain period…

Sometimes, the thought of loosing something can motivate action! 🤓
It would be nice to have the ability to LOCK a course after a certain amount of time (eg 2 days) so the student knows s/he has a limited amount of time to go through a particular lesson!
Can definitely increase completion rates of courses! (plus provides the dual functionality of using the courses feature for challenges!) 😏
