Actually, I know how to use it, and I realise you could just run it multiple times.
Thing is, if the goal is to automate this process, why not be able to automatically add every empeg found on a network without having to maintain a batch file if someone brought in a different one? Since this is a client utility, if the three of us each have several people listening to our stuff, and we happen to bring in a different machine (with a different serial number), many people would be required to update their batch files.
If the feature I requested was implemented, this goes away. Just an idea for those places that have several empegs.
