I cannot add scale body parts to pose. When I'm loading pose from library bend/side/twists are ok, morph chanels are ok too, but scale added to body parts never load. Is it normal Poser performance or I have bug?

I've read here that I can add character to library and later copy cr2 to pose, changing extension and deleting not necessery parameters from file. Is there any way to add pose to library "normal" way?
