moving the center of rotation in peg

when i try to rotate randomly the object it works great, except that the center of the rotation in peg layer is set to center of frame, how can i change the center of rotation in peg to center of my object , just as it is the the object layer.

oh I found another way, i apply randomly fill exposure to the angle column of object not its peg.

For the rotation point of a peg, you can move it using the Rotate tool. This will move the anchor points for all frames, however, since a peg is not related to a specific drawing.
