Thanks for your response @Chris_Hofer. I'm a bit confused because in all the examples in the link you posted, either you can assign to Everyone, to individual students, to a Course Section, or to a group, but not to a group set. I should add that I don't see any option for GC1 in my "Assign to..." box.
If I don't change the "Assign to..." box (i.e. if I leave it as "Everyone") then all students will be able to see the assignments for all of the group sets, right? That's not quite what I want-- I want the student belonging to a particular group set to only be able to see and submit to their corresponding assignment (there are only three different versions of each assignment, corresponding to the three different group sets).
