When some limbs are getting mistracked, manually correcting them usually is the best way to do it.

Edit>Copy Pose was useful but if the actor is in complete motion, every frame is unique from each other.

What I want is the ability to copy only a range of body parts I need that I will paste to the next frame so that I will spend less time doing it.

Since DMC usually only fail tracking an arm or two. I would like to copy only the shoulder, forearm and hand and paste that pose on the next frame.
