Saving location should be user selectable in network mode

Why isnt it possible for the user to select the save location?

As far as I have figured out it is only possible to define a save location on the server side. This should be user selectable via a pop up. Reason for this? When sensitive or personal data is being printed it is unacceptable that the pdf is being saved to a public location. Also that the filename cannot be set by the user is not all that convenient.

Did I get it wrong, or are these things just not possibe with this pdf creator?
