Linking Part Properties to Document Properties

I am setting up document templates for one of our engineering groups and I am having problems with properties.  Is there any way to have the custom properties from the part model follow into the custom properties for the part drawing?  When I try to upload the drawing into our vault, it keeps showing as missing properties.  The properties are the same for the part model and the part drawing, so I don't want to enter them twice.

Thanks,

Matt
