It would be helpful if the courses that are added to a curriculum retained their due date rather than the due date defaulting to that of the curriculum.
For instance, if a curriculum has 5 courses, and they each have staggered due dates (30, 60, 90), that should be visible on each course within the curriculum versus the overarching due date for the curriculum.
Especially if there is no curriculum due date, this would be a great asset. I understand why you can't have both active at the same time, but one or the other makes sense.
