Custom photoworks materials in custom solidwork materials

When you create a custom solidworks material it's possibletoassign a photoworks material to it. But it seems that you cannotassign a photoworks material you created yourself. I want tomake acustom steel material with orange color. When i renderlargeassemblies I don't want to assign photoworks materials to alltheparts. It would be so sweet if a custom photoworks materialcouldbe attached to my custom solidworks material.

Does anyone understand what I mean? I would be amazed ifthiswasn't possible.

Thanks in advance!SolidworksPhotoworks
