Is there any way by which I can create an assignment for some students but not for others? For example, we want to allow students to only submit responses for 10 assignments throughout the course, but the students can choose which assignment to submit. So some students might already have 10 responses, so they should not be allowed for submitting responses to the other assignments. Since it's quite a big class, so we don't want to identify which students have already done so individually. Any way to solve this?
