Yeah. You don't need to go to Zbrush to do that.

Zero your figure.

Dial the expression.

File export wavefront object. Select the head only. Leave everything unchecked. Reimport to head properties as morph target: load morph target. A morph dial will appear in head that contains only the deformations as a morph. In the head. Not as a PBM or FBM, totally unnecessary, that GoZ will create. Poser 101. Load morph target.

Remember I said this?

"If redistribution is a thing I would bake down my control chip expressions to morphs. File: Export: Wavefront Object: Head. All options unchecked. Apply export as morph target. There's your expression baked down to a morph. Up to you if you want to copy centers to. For expressions I wouldn't bother."
