I'm not sure if this is what you mean by Poser and the  the jcm dials or not.

I am running version 7 of Poser and this is a screen capture of the parameter dials on Toni.

It doesn't show a parameter dial for just the jcms, they are shown just like these image indicate.

Let me introduce you to my multiple personalities. :)
