I don't know about V4 specifically, I don't have her, but every channel in a cr2 has a switch "hidden" which can have a value of "0" = not hidden, or "1" = hidden. You can change this value, either by editing the cr2 directly in a text editor, or by applying a pz2 (pose) file in Poser. Below is an example of a pz2 that will unhide translate dials for the leftEye, and hide them for the rightEye.

{
version
        {
        number 3
        }
actor leftEye
        {
        channels
                {
                translateX xtran
                        {
                        hidden 0
                        }
                translateY ytran
                        {
                        hidden 0
                        }
                translateZ ztran
                        {
                        hidden 0
                        }
                }
        }
actor rightEye
        {
        channels
                {
                translateX xtran
                        {
                        hidden 1
                        }
                translateY ytran
                        {
                        hidden 1
                        }
                translateZ ztran
                        {
                        hidden 1
                        }
                }
        }
