I'd like to assign an Assignment to all member of a Canvas Group.  This is not a group assignment; I want each student to do it individually, however I only want certain students in my class to do it.  I thought I'd be able to do this by selecting a Group when I got to ``Assign to," but I apparently cannot; the groups just don't show up anywhere.

Is there really no way for me to assign an Assignment to members of a Group?  Do I always have to add students one-at-a-time?
