Path settings of spark

Hello
We used thePSIin theclientcompanyfor some time now. We tested thesparkand foundmuch better than thePSI. One of the difficultiesthat I realizedthespark, is thatall the settings(propertiesand historic..)recordedin the user profile.Would you liketo changethis path.Thusany userto loginat the station andaccess thespark, all thetalkingare in the samefolder.
You can definea foldersettings(properties/historical..) whenthesparkstartsthespark? I want to makethe folder c: \documents\spark\config, for example.

Thank you.
Antonio
