Webport: uploading input files to @JobDir instead of @UserDir?

Hi --

Is there a way to configure webport protocols to upload input files to @JobDir? I couldn't find a way to upload input files to @JobDir instead. (And, I couldn't find a way to omit @UserDir in general.)

Background: Our webport users never run PP clients, thus a @UserDir isn't needed at all. Keeping input and output files in @JobDir only would help to omit stale files in user dirs that couldn't be removed by the webport protocol because it crashed, ran into an unforseen errror and such.

Thanks for your help/advice.
