I was playing around with HeadShot V2 (photo method)

How do I go about using HeadShot to update face, but not body?

For example....
1) If I use HeadShot to generate a face, it will also update body.
 2) If I go to Human Anatomy, to update body, it deletes the HeadShot face.
If other words if I use HS first then update body it will delete the HS face.
Or if I do it the other way around,
If I use HA to update body, and go to to HS, it will delete the HA body.

So
HS->HA : HA deletes HS face
HA->HS : HS deletes the HA body

How do I do this? And in which order?

thx!
