I am sorry guys, maybe my description of the problem was not clear....
OK, I have a part template let's call it GoodTemplate which has some Configurations specific and Custom properties set in it.
I created partB which is a copy of part A.
Part A was created using some template that I do not care about.
I want part B to have Configuration Specific and Custom Properties same as GoodTemplate.
I hope I described it better what I am looking for.
Sorry for the confusion again.
