Zero or remove face morphs only?

pcfixer_6eeae1419c

I have a variety of characters that I've created with V4 and sometimes I want to apply a new face while retaining the body shape. The problem is that with an existing face morph or dials the new face doesn't look "right". I've searched and searched but been unable to find any info on removing the morphs or dial settings of just the face. (Of course I could go through and zero all the face dials one by one but what a pita, morphs aren't so simple) Is there a way to do that within Poser, or with a third party utility?
TIA
