I've gone through the document here
And I can't get it to do anything useful in my course. I have 21 Sections, and I've created three Groupsets each fully populated with subsets of students.
No Matter that I set my gradebook filter to, it always seems to pick one specific Student Group as the entry point, and if I try to change, It shows me Sections, regardless of what filters I have active.
TL;DR, I don't think this feature actually works just yet.
Is there any better documentation on this feature? Or can someone point out what I'm doing wrong?
