Option to lock portions of lessons
I would like to be able to lock portions of lessons. For example, my introduction on Mondays might always be to do a section of habitudes. However, then we continue with our lessons. If it gets bumped because of a snow day, I don't want the introduction to be bumped because that is only on Mondays. The same is true if I always have a quiz as part of my lesson on Fridays. If I have a snow day, I don't want the quiz bumped to Monday, just the lesson.
