@TracyAnderson73 - I am not sure exactly which classes you are referring to that you need to scroll through, but in that drop down for copying an assignment, you can type search terms - i.e 2025 Then only courses that have 2025 in them show up. It would depend on how your school sets up the course names if that will work. You might even be able to type in the course number (i.e. 211 ) and see only those classes that have 211 in them.
One way you might be able to help yourself is on the dashboard give your course a nick name: I use Year (i.e 2025) - Semester(Fall, Spring, Summer) course reference (i.e CPE200-02),
so my course names on the dashboard and the copy list look like "2025 - Fall CPE200-02"
I am not sure, but you may already being searching and you have so many courses showing up that it is still a long list to scroll through.
Hope this helps in some way.
