FME Server Data Download configuration

In FME Server 2011 SP2, how do I configure the data download URL sent to the requester in the email, to show/use a preconfigured name in the URL versus the actual server name and port? For instance the download URL may look like this: http://myrealservername:80/fmedatadownloadresults/FME_7F685958_1352851611722_5036.zip. How do I configure it so that I can alias the server name and port for something other than the actual server name? Also is there a way to allow the user to name their FME results so it's not a long list of numbers/characters for their zip file (which would also make it easier to find specific log files when debugging workspace results)?

 

 

Thanks!
