Make copies of server.bat, server.sh or whatever you use to launch it, then use the -C switch to set multiple servercmdline files, such as
-Cconfig/servercmdline1.txt
-Cconfig/servercmdline2.txt etc...
By default, it will use servercmdline.txt found in /config.
Alternatively, make multiple launcher scripts with different switches for each (ex. server1.bat, server2.bat, server3.bat).
