GPO setting for My Places bar in Office

[ender`]

Is it possible to set the shortcuts/folders displayed in My Places bar in Office applications (specifically, Office XP and 2003) through Group Policy? I know where to set them for standard dialog boxes, but Office applications use custom settings. I have looked through the ADM files provided by Microsoft, but couldn't find these settings, and searching with Google only gives me pages which tell me how to edit the registry on local computer.
