I'm having students work in long-term groups over multiple assignments. The group assignment functions work great, except when one student flakes on the others. While usually I want everyone within one group to get the same grade, if one student doesn't do one component, but comes back to do group work on subsequent assignments, I need to be able to ovrerride that individual student's grade to account for the work that they missed but that their partners did not. Right now, it looks like I can't change one person's grade on a group assignment without also changing the others or without deleting the group entirely, along with all their submitted work.

Is there a way to individualize grades as needed within a group assignment?
