how to create a head slider

tomasball

I know how to use morph loader to add a morph to a character.  What I would like to do is create a morph that appears as a slider in the head / pose controls section.  Is there a way to do that?

BTW, pls make sure the morph is really a Pose Control morph, 'cause if you zero figure's pose, morphs in Pose Control path will be zeroed.
