[Help] Where is the (block) 'keyword' setting? - eviltoast

I’m now at the point where my blocklist of communities is a multiple of the number of my subscriptions. A lot of my blocked communities have similar or even the same titles across different Lemmy instances, e.g., ‘politics’, ‘news’, ‘memes’. New ones pop up every time I visit ‘all’ and it would be so nice if I didn’t have to go through blocking each individual one each time. I understand that nobody has a working regex block at the moment but I’ve seen mentioned in several places that LemmyConnect has a keyword filter. Please can someone show me where it is?

Thanks
