Cadkey19 to SW2009

I have a assy. that I did years ago that I need to bring intoSW2009 SP3, it imports ok but... it now is a assy. and has nomates.

What I can't figure out is how can I use Feature Works in a assy.without having to open each part (about 200) rename and thenrebuild the assy. and try remember where they mate from 10 yearsago from the ground up.

Is it even possible?
