Alien Disguise in CAS

So, now that we can create our disguise while creating aliens in CAS is there a way you can copy the alien face directly onto the disguise (or vice versa) so the nose/eyes/lips/etc. match perfectly, or do you have still have to manually edit everything?

I know some people like to have the human disguise look nothing like their alien self, but I'd like them to match as closely as possible.
