Autosave and windows environment variables?

I've installed PdfCreator on a Windows 2003 server and it's shared as a network printer to windows clients (XP and Windows 7).

The problem is now how to save the created files to make it understandable for the end users. Isn't it possible to specify a auto-save directory with windows environment variables like %USERPROFILE%\\Desktop? 

Or maybe another better solution: Any plans of letting networks users get a dialog of where to save the PDF-file instead of the auto-saving requirement?

We described one solution in the help file -> Using PDFCreator.

Another way would be to use the auto-save path:
\\\\\\c$\\MyPDFs\\\\
or
\\\\\\c$\\Documents and Settings\\\\My Files\\MyPDFs\\
or
\\\\\\c$\\Documents and Settings\\\\My Documents\\My PDFs\\

and so on. (Be shure that PDFCreator is always started on the server and it is started with a domain admin account.)

Not at the moment because that this is not simple thing.
