Copying a Part and Compressing Features, but keeping defined surface & sets?

Hi

I've got a very complicated component which has thousands of Features, when regenerating it takes ages ( i've already changed the tools>options etc to speed it up)

I know i can copy the part and compress the geom features, however i want to keep the surfaces & sets i have defined for loading and connections to other parts..

Is there a way of copying that data from one part to another?

thanks for your help
