Buddy Press - Favorite plugin - is there one available - or can we create one

Hi,

I'm looking for a buddypress plugin (for wmpu install)

that places a tick box next to each blog name in the blog listing
"add to favorites"

that places that blog in a new listing in the user profile
so when a user goes to their profile
they can select "favorites"
and this will provide a list of blogs they have added. enabling them to click and go straight there

just wondering if such a plugin or something similar exists
if not I'll be happy to look at a quote to have one coded up.

it could be then extended later to include groups etc

cheers,
Steve
