Different asignment dates per group, or unique assignments per group

When students are enrolled for the same programme, where everything is the same except for different schedules it is necessary to to specify assignment dates per group, or at least set unique assignments per group. While one could create separate courses in Moodle Learners would then e.g. not be able to participate in the same course forums and other activities. This functionality would also be more consistent with Groups functionality in course forums.
