Ability to manually assign rooms instead of always automatically grouping students

For Sync and Async Rooms, it would be nice if teachers had the option to choose if Extempore Groupings are assigned Automatically (current functionality) or Manually (new). There are times when it is a lot easier to manually create the rooms compared to rearranging the automatic assignment of rooms.

• If Manually assigned, all students would go into an "unassigned" bucket for teachers to assign them to rooms.

  • Newly enrolled students would be "unassigned" by default which would help add them to a group of students that hasn't completed the task yet.
