I have many sections (15) in my course. I'd like to create groups that would be comprised of the different sections. So, one group would have sections 1-3, group two would have sections 4-6, and so on. I don't want to select individual students to put into the group because students may add or drop the class after I create the groups and then they would be lost. Is it possible to make a group comprised of sections of the course? If so, how?

Thanks!
