Record Feed Widget - Select a Category

I feel this is an oversight when the record feed widget was made, but you should be able to filter records by category (or "all") like other places have the option to.

In the screenshot below, the only filter options are generic database things that don't help with what I'm trying to accomplish; the other options include the generic "pinned," "featured," etc filters. The database 'Server Rules' has categories for each game server we host so I'd like to have "Game A" rules on one page, while I have "Game B" rules on another.
