The session name can be changed when the server is started with -sn name. So what you can try is to get all the info for the server from the client that wants to create the server and then start the standalone server minimized with the new session name. Then when the client who created the server disconnects you close down the standalone server, as in exit it completely. If the client wants to create a new server you can change the session name again via -sn name when the new standalone server gets created.
