Is there a way to not see a specific feed on network?

[chalcopyrite]

Someone on my reading list subscribes to a feed that dumps several pages worth of entries I don't care about on my network page every evening. I know about ?show=PC, but that strips out all the feeds and sometimes there's something new I want to see. Is there a way to cut one specific feed out of my network page? Or should I, hmm, subscribe to that feed and then filter it off my reading page? (Solution that just occurred to me.)

(I have checked the FAQs, but since I'm not sure what to call what I want to do, I hoped this might be a shortcut.)
