Aggregate all subscribed to subreddit’s into a single subscription

Hi,

What I’m trying to achieve is a single subscription within NetNewsWire showing all new posts from subreddits my Reddit account is subscribed to.

What I’ve been able to do so far is add single subreddit’s by adding .rss to the end of each community, but haven’t found a way to automatically aggregate them all under my username instead.

Has anyone had any experience with this?

Maybe a feature request for future versions of NetNewsWire?
