How Auto placement of COG using relations, can be done?

Question

Using relations, I am trying to place coordinate system or point at Centre of gravity of the part. As I change the part dimensions, the COG changes & I want to move the placed co ordinate system or point automatically. I used relations
 
$D13 = mp_cg_x("","CS1","")
$D14 = mp_cg_y("","CS1","")
$D15 = mp_cg_z("","CS1","")
 
$D16 = mp_cg_x("","CS1","")
$D17 = mp_cg_y("","CS1","")
$D18 = mp_cg_z("","CS1","")
 
but nigher coordinate system nor point getting placed correctly at the center of gravity of the part.
Eventhough I have maintained congig .pro option "mass_property_calculate" as "automatic".
