Possible to snap vertices to Symetric Axis?

[pkd]

As titled, is it possible to snap (not eyballing) vertices to the dead symetrical center.

Smart symetric works expect for the roll of vertices that is suppose to be (0,x,x), for perfect mirroring purpose.

I can do it via third party GoZ or something but it would be nice if there is an option within Zbrush.

I wrote a plugin to do this which you may find useful:
