Add Materials to Render Library

[azmz3]

Is it possible to add new classes to the Render Libarary in RAC 2009. I have downloaded the Dunn-Edwards Color book for AutoCAD and would like to try and load it into Revit in its own section, instead of in the paint area. Does anyone know if this is possible?

You can create new materials based on the shaders that ship with Revit but you can't add shaders to the rendering library.
