THe easy way is to export the parts of Don you want as an object file with Don set in his default pose, saving the group references of them. Then import it into P5. Go to the setup room and select Don as the bone set. When you go back to the pose room, you'll have a Don figure, fully posable, with only the poly's you saved. No mussing in setup room at all if you save the single object file in the default pose.
