Ok, here's what you do but I've only tried this with hair. I bring in the hair .cr2 and instead of conforming I go to the Figure menu/Set figure parent and choose the head of my character. Once it's parented I save it in the library with a different name so as not to overwrite the original.

Then navigate to the folder where you saved it and change the .cr2 to .pp2. Open it up in a text editor and find the 2nd instance of actor BODY. Below that you will see many entries. If you compare the .cr2 and .pp2 you'll see the .cr2 has "parent UNIVERSE" whereas in the one you saved and changed to a .pp2 it has "parent head:1" change this to "smartparent head:1. Resave and open your .pp2 in Poser. The .cr2 will come in and be parented now - no need to conform.

Hope this helps!
