Is there a way in the Edge browser to retain my current cookies from a small list, but delete the huge bulk of others? [View all]

I have built up, through carelessness, a vast list of cookies - so big that just getting a list of them seriously degrades performance, so that deleting each unwanted site individually is not feasible. I'd like to allow about 30 sites to set cookies - and to allow them to keep the current cookies they have set, so I don't have to log back in to them, reset preferences etc.; and delete the thousands of other sites.

Is there a way to do this? Everything I've found so far implies I have to say "delete all cookies", and then build the cookies from allowed sites back up again, which may involved much tedious logging in etc.
