Import Surface Symbology (InRoads SS2)

Something that I had never thought about before and have not been able to figure out how to do so.  Is there a way to set the surface symbology when importing surface from graphics?  I know there is a trick to having the surface symbology set out of roadway designer (creating a preference with an identical name as your desired symbology) but I haven't been able to make that work importing existing graphics into a surface.  Thanks for your help.
