SS10 - ProjectWise File Path and Name in Pentable or Design Script?

Hello,

I am trying to get the ProjectWise folder path onto our plots. If I use the file long,  resolves to c:\ <pw working directory>\dms123435\testfile.dgn
Is there a way around this? We had a fix for this in SS4, but that no longer works in Print Organizer in SS10. Works for single plots, but not in Print Organizer.
Tested named expressions, but they resolve to the PW working dir too.
Any thoughts appreciated.

Thanks,

Tom F.
