Modifying SLDPRT document settings from the parts drawing(SLDDRW)?

For example, lets say a single part is open as a SLDDRW. I want to modify the parts .SLDPRT document settings and not the SLDDRW file settings. Is there a way I can grab the .SLDPRT settings while in the SLDDRW? I want to run a macro that does this from any current .SLDDRW.
