how to blacklist (or better, whitelist) languages? also countries or subjects?

Lately I've been seeing a huge amount of new Lemmy subs in different languages, or subs specifically about certain regions, countries, etc.

I very much applaud this growth, and think it's awesome that so many more people can enjoy posts in their own languages.

Having said that, 50% of the posts I see now are in languages that I don't remotely speak, are specifically and only for countries on the other side of the world for me, or are about subjects I really am not interested in ) mainly anime.. so much anime...

I keep blocking these subs when I see them but they show up faster than I can plug them, and my blocklist ia getting larger and larger and honestly bits becoming a nuisance

Is there a way to at least whitelist languages? I speak a good amount of languages but giving me twenty posts in twenty different languages is just... Not working

Also, if we could perhaps tag subs with labels like "news" and "anime" I could then whitelist or blacklist those tags that I like

Is there anything like that available on Lemmy?
