I am new to setting up my classes. I created a class for all my trumpet students, but I have been differentiating their assignments. Even though I might assign an exercise to 2 trumpets, all my trumpets see it on their dashboard. It is becoming confusing for them to see 4 songs when only one was actually assigned to them. How can I fix this? Can it be fixed? I do not want to have to narrow down my classes even further. Can I rename the exercise after I already assigned it to make it easier for them to find it, or will I have to reassign it?
