A featured global posts plugin???

Say I have a site set to contain posts on various topics. I have it multisited and broken down into the blogs I want:
Site1 - Fishing
Site2 - Boats
Site3 - Bait

Articles will appear under the specified categories for each site. What I'm searching for is something similar to the Recent Global Posts widget except I have the ability to filter which posts I want to appear. So in widget 1 I'd select latest posts from the Boats site and widget 2 posts from the Bait site etc. Now if you're on the Boats site in the footer area you'll see latest posts from the Fishing and Bait sites. Right now I see latest posts from ALL sites and I really don't want that so I'm hoping someone can provide a way to have this.

Any responses appreciated
