get delta value of node center point (when fit to) ?

Hi when figure A (eg Hair) fit to Actor,  nodes of Hair are connect to Actor rigs which have same name. (may need keep hieralchy) then if Actor deformed by morph or controller then change rig, figureA rig change too.

Eg,, now I change genesis3 size, by HeightMorph . which have ERC to change genesis head rig center point and end point location to much with current morphed shape.

then  head node of Hair ,   it center point and end points will follow current genesis3 head node position. It is reasonable.  But Is there way to get those current node cenrter and end points position delta, about figure which fit to and changed by Actor morph,  as actuall parameter value, in daz studio?

I think, when figure (hair or clothing) fit to another figure, and morph change Actor rig center points, end points,  follower (hair) rig center point value seems not change as visuall value in parameter tab.  (though I can clear see, hair head node center point ,end point follow the genesis head rig,  anc change location,,)

But in parameter tab,  it seems keep default value.  then is there way to get those node (rig) position delta value which deformed another figure morph with  fit to?  

Of course I can check the delta value to see  how head node center point change with morphs, by  parameter of genesis3 ,  but it is not so useful, when I need to set ERC with those delta value  of current  Follower figures.

eg I hope to set morph for ghost bones child of head node of hair, then I hope to set ERC with current head rig center point, and end point, then auto move those ghost bone too.  without it,, hear ghost bone not follow current head node position.
