It depends on how the merchant loaded them.  But you can always save a pose again without saving the morphs and/or the transformation.  When I do that, I give it the same name but add NM to let me know that pose has No Morphs (and no transformations).  For instance "Sitting back NM".

Note:  A good time to save the pose with the body transformations is when you have two figures positioned very precisely with each other.  For instance a man and a woman dancing together.  Or two figures shaking hands.  Or two figures kissing.  If you don't save the transformation with the pose, the figure will assume the pose wherever it happens to be standing, and sometimes trying to move the two figures back in that intricate dance pose or the two hands to grasp each other again is very difficult and frustrating.

But if you save the body transformation with the pose, the figure will assume the pose AND move into position.
