odf, I use the putty tool in Poser 7 to fine tune my Face Shop morphs.
It takes a little practice but it works.

Not sure on the vertice thing but I believe someone said you can.

I've been using it tonight to fine tune my older woman morph for Antonia.
And I've saved it to a pose file now and almost finished the full texture to go with ti.

As soon as I can do a bit more, I'll post it to the developer's site so folks can check it out.

Let me introduce you to my multiple personalities. :)
