Is there a mod to restrict axis of a gimballed rocket motor?

Something similar to the pitch, yaw and roll buttons for control surfaces.

 

EDIT: Just in case someone finds this in a search one day.  The answer is IT'S NOW STOCK!  As of 1.1 I think, just right click the engine, clock "Show Actuation Toggles" and pick/choose which controls will and won't gimbal the motor.
