[launchd-dev] How to run a few instances of a daemon (agent)?

Hello By default, launchd starts a daemon or an agent, by doing the following 1) either "launchctl load /path/to/daemon.plist" is executed, or the plist is loaded automatically when the system starts 2) "launchctl start" is executed (if <string>RunAnLoad</string> is set to <boolean>false</boolean> then, only one instance is being run. I am wondering, if I could run several instances of the same daemon or agent (using launchd). Would it be possible, or I need to daemonize the process by myself, using an old unix way? Thanks, Nick
