Possible to Link Parts and Drawings With Different File Names?

I've searched and have not found an answer for this and have tried a few different things.  Basically I need to be able to maintain a link between a part and its drawing file but both the part and drawing have a different unrelated name (I'm working with outside files and am not allowed to change file names at the moment)  Essentially when i have the part open and right click in the tree "Open Drawing"  I have to browse for the draing manually, when i do find the drawing the link seems to be maintained for as long as the part/drawing is open, but as soon as I close and reopen i have to manually browse for the drawing file again.  Any help would be greatly appreciated.
