If the material settings are proceedural, right click and select all to high light all the nodes.  Then right click and apply to all.  This will apply the proceedural to all the material zones.

If you are using a material that has different texture maps for different material zones, you can select the nodes, pull down the material zone list at the top right, select the material zone you want to apply the selected materials to, right click and apply to.

Depending upon which version of Poser you are using, there is a script by Poseworks called ShadersSpider.  If you want the source code it's now free through Google code or something like that.  If you put ShaderSpider in Google, you should find it.

If you want the exe and presets, it's still for sale over at DAZ.  I haven't tried it in Pro 2012 but I had it working after a fashion in P8 and Pro 2010.  If you have P7 or P6, it works fine.
