Is there any kind of hook or method of triggering a script when garbage collection finishes? I have my datastore configured to do a prune, followed by GC, and then I want to trigger an rclone script to push a copy of the datastore to Backblaze B2, but I would greatly prefer this to be triggered by GC finishing instead of a cron schedule. I don't think PBS has anything like this built in, so consider this a feature request, but is there another way to accomplish this? I can probably come up with something, such as watching the task logs.
