i do it this way....

1)create a V3 with all the headmorphs injected; save to a library as "face figure;"

2)create a character using "face figure;"

3)spawn a morph to the figure; i also save the dial poses to a library for a later date....

4)save the new figure--either to a new library or as a .pz3

now i can use a "morph manager-style" program to delete any unwanted/uneeded shaping morphs from the head (or just use the appropriate "remove all" poses); leaving me a V3 with the new face....

this probably takes longer than momcat's (hi momcat!) method, but it works for me....
