Try applying them in the material room and then saving the pose.  I haven't seen anyone do this since P4 because it was a way to keep the runtime textures folder from getting too bloated.  The mat room is the place to apply the textures.  Or, you can move the .cm2 files into a pose folder and change the extensions to .pz2 and you'll be good.

This may be a little more work but it saves your poserstyle textures for you, thus not useless.
