How to use %homeshare% for directory path when using Auto-save

While working with the latest version of pdfcreator I'm looking at using the autosave option for print to pdf. Current configuration:

I have installed the PDFcreator on a print server and setup the install as a network printer.

I then installed the printer on a number of terminal servers so when they need to print to the PDF printer they can share the same process.

My problem is I want to beable to take a print job concvert it to pdf and place the file in the users homedrive using the variable %homeshare% this would allow allow for each of the pdf's created to be dropped into the correct users folders
