There are no tools to sort through subscriptions that I know of. I am subscribed to some channels that put out tons of contents where I usually don't want to watch it, but the stuff that I do want to watch is high priority, channels where everything is priority, and channels where it's content I just want to watch occasionally when it happens to show up and I'm in the mood.

I learned long ago that anything I want to watch more than once should be saved locally when a record label made a group I liked delete all their content to promote a new album, but I need a solution for filtering the one time views.
