Apply Filters to All Feeds with a Label

Is there a way to apply a filter to all feeds marked with a certain tt-rss label? I have a set of filters I would like to apply to about 75% of my feeds across all categories. However, I don’t want to specify each feed individually or sort said feeds into a single category. If I could just label each feed to be filtered, it would solve this problem.

Please let me know. Thanks!

labels are applied to articles not feeds, use categories instead

Ah, okay. I had misunderstood. Thank you very much for taking the time to respond!
