Groups in Students' namespace

I’m using the assignment model wherein students create a private fork of the assignment and add me as a member so I can view for grading, etc. The issue I have is that students often forget to add me to the project, and so I’m having to contact students manually to get added to the project. I would LOVE if the students could create a group in their namespace, ie that would allow them to make me a member of that group ONCE, and then they would put all their forks in that namespace. Would help a ton for students who take several of my classes, because currently, I use simple slugs for assignments (ie. ‘hw1’) which would collide across classes.

I cannot find a way to create a group as a child of the user namespace.
