How to import Pose from DAZ not Model

I just successfully imported T posed fbx file from DAZ export.
As a next step I need some pose / animations that I can use mecanim.

However I don’t need model data for every poses. it is waste of file size.
What is the best way to import poses without model data and apply them to one T posed model? I’m not sure how I can export just pose from DAZ studio…

This sounds like a DAZ question rather than a Unity question. Most 3D software will allow you to specify what elements to include when exporting to FBX - meshes, textures, animations etc. You just want to include skeleton/animation data.
