[Closed] constraining uvw/vol select mod. gizmos

I need to position constrain a couple of uvw and volselect modifier gizmo’s to inherit the animation from a seperate piece of geometry or dummy.

I managed to assign a position controller to the gizmo via the curve editor, but it is always locked and i cant seem to get into the properties to link. Does this need to be done with scripting and if so can somebody help me out cuz i cant seem to get this to work yet…
