Included in the 'Dynamics for Nuke' plug-in set, there is a utility node that
un-transforms geometry.
It was originally designed for shifting center-of-mass on imported geometry but
might accomplish what you want.
First it computes the object's current world space center.
Then it transforms the object's points so that center lies at the world origin.
And finally it puts a matrix on the object to shift it back to where it was,
and gives you a zeroed out matrix-knob you can then adjust.

if you want to
move this
further or
rotate a
specific
amount
relative to
this, just add
another
Translate
between the
object and the
current
transform.
For this
reason I very
rarely do
transforms in
the actual geo
transform
knobs. As
long as you
put the
transform
nodes in the
correct order
you won't have
problems with
things
rotating
around 0,0,0.
