not that I know of. someone had a recent question about all. My personal strategy is to peruse all and block communities I have zero interest in. Like I have no interest in sports so I get rid of all those. Concurrently I subscribe to things im really interested in. I put blocking first because it reduces what you see so makes it easier to find what you really want. Once you have subscribed enough you start your scrolling day in subscriptions and when you run out you go back to all and maybe you come across something new to subscribe or whatnot.
