Force grappled foe prone?

[Poison Dusk]

Last night I thought I saw a feat(Teamwork?) that allowed you to make your opponent, yourself, or both prone while grappled. Am I imagining this? If not where can I find it?

I suppose It doesn't exist. I can't find it anywhere now.

Death Roll?

EDIT: Also, the Raging Grappler rage power.

Raging Grappler was it. I thought when I read it the first time it was a feat. Easy to get confused when I did a search for "teamwork feats". Thanks a lot!
