Allow subscription to the same url multiple times to allow different filtering rules

[guest20]

Some youtubers upload their 9 hour stream vods and edited stream hilights to the same channel.

I'd like to subscribe to to that feed url twice so I can have one subscription filter out the stream vods and the other filter on them:

  Feed url: youtube.com/steve.rss  title: Steve Vods      Keep: "itemTitle=!donate.*🔴,*LIVE"   category: "stream vods"
  Feed url: youtube.com/steve.rss  title: Steve hilights  Block: "itemTitle=!donate.*🔴,*LIVE"  category: "video essays"

Ideally I'd like these two subscriptions to not do their own requests to youtube (since their rate limits are aggressive) but being able to split a feed into categories based on rules would be nice.

This could be implemented as a "✅ Let me subscribe again..." option under "► Advanced Options" when subscribing (Possibly automatically adding (Copy) to the end of the default title.

• I re-read the "opinionated" doc and don't see another issue like this
• I am a number of versions behind on miniflux, so apologies if there's already a feature for this
• My feeds are a huge mess, so there's a good chance I'm just snowblind and there's a more obvious way to do this
