Can I set a viewer group to only see .dwg and .pdf files in the PDM?

I believe I was told by our reseller when installing PDM that viewers could be limited and selected for what file types could be viewed.  I want to do this as non solidworks users don't need to see solidworks data.  PDF and DWG's are the masters for manufacturing and the prints for downstream viewer use.

Thanks,

Ryan
