Cleaning Up GH Classroom

Hello! The GH Organization that houses my classroom is cluttered with repos that were created from GH Classroom when students submitted an assignment. I have about 60 repos that look something like “BST692_A1_[studentUsername]”.

Last summer was the first time we used GH classroom for teaching. Does anyone know of a better way to do some housekeeping. The repos are private so future students won’t be able to see past student submissions but it’s an absolute eyesore to go to my org page and see 100 repos of past students’ assignment submissions. Any suggestions?

I really do not want to manually go through and delete all the repos.

Thank you!
