Can't delete Add-on files or bundles for Oculus Quest app.

Is there a way to modify or delete Add-on bundles or individual DLC files within bundles?

We want to start using Add-ons instead of re-uploading DLC files with every app update, so we created Add-on 
bundles in  App Manager -> Platform Services -> Add-ons and uploaded some test files to experiment with, however we have discovered that there seems to be no way to delete these test files from the bundles, or even delete the bundles themselves. There is an option to leave them unlisted, but these unused test files are still associated with all future app versions and appear in things like Asset File fetch requests.
