How to change NDC in a pad?

Dear ROOTers,
I have the following problem: I have drawn a pad which contains several different pads. Now I want to make room for other pads and to do it I thought it was possible to change the scale of the “mom” pad with Range(). But every time I draw a pad the coordinate system used is NDC, so they children pads will remain in their position while, for example, TPolyline objects will change their position inside the mom pad.
Is it possible to draw a pad using a different coordinate system then NDC? or is it possible to change the NDC range of a pad?

No this is not possible.
By definition NDC is in [0,1] and subpads are defined in this system.
