Currently we have a different situation where we have groups assigned to automatically to courses. We are unable to utilize the due dates because of this as someone could sign up for a course right before and not have the total amount of due dates as the other's who where already signed up earlier.
We need to have an option to assign multiple due dates to a course and then the ability to assign those groups to the specific due dates. i.e. group a would be 3/13/18 and group b would have a due date of 4/1/2018.
