Train on target URL

[jgbishop]

I would love to be able to train a feed on the target URL of an entry. This is primarily motivated towards RSS feeds that aggregate stories from multiple websites (e.g. Hacker News, Slashdot, Kagi small web). So, if an entry from site "example.com" shows up in the feed, I'd want to give it a thumbs down to block it in the future. Is this doable?

+1 vote for this, though in my case I would like to filter by URLs on the same domain.

E.g. to see posts with the URL https://www.example.com/news/newsletters/*

but not see ones with the URL https://www.example.com/news/articles/*
