You could also spawn a morph target as well. I am not in front of Poser at the moment so I am going from memory here but if you select the head (and I also recommend the neck as well) and then select Create (or possibly Spawn) Morph Target under the Object Menu at the top of the screen it will create a single dial which you can name that will re-create the new face when you set it to 1.0. Don't forget to zero all of the head and neck morphs before you apply the dial because if you don't it will add the dial to the active morphs basically doubly the effect. The same thing can be done to create full figure morphs using Create (Spawn) figure morph under the Figure Menu.
