I put process in another thead .

In the material room Save a mat or material collection (mt5 or mc6)
copy or move to pose library from Materials library (using windows explorer)
rename to pz2
edit in wordpad or notepad (or other plain text editor)
change mtlcollection line to figure (if its a figure) or actor $current (for a prop)

simple

a material collection will do from 1 to many of the materials for the figure or prop so you can control just what you want changed.
