Linking assembly drawing notes to part properties automatically.

I'm trying to figure out how to create an assembly drawing template that will automatically populate part properties in the notes.  These will be mostly sheetmetal parts with some PEM hardware.  I want the notes to be able to call out the material and finish I've set in the base part (not the hardware parts).  I know I can set that in the custom properties in the assembly but that's not what I'm interested in.  How can I use "SW-Material@Some_SolidWorks_Part.SLDPRT" in a drawing template and have Some_SolidWorks_Part.SLDPRT update automatically to whatever the part is?  I realize Some_SolidWorks_Part.SLDPRT would need to be a variable but what variable (assuming this is possible).
