Multiple episodes, one file

I'm trying to rename my star trek collection so that it conforms to the plex naming standard. But I've run into a snag. I've named everything like so:

Star Trek Voyager/

  Season 1/

    10 - Some episode.m4v

Now, with some episodes, it's actually 2 episodes in one. And according to the guide, it should be:

  Star Trek Voyager - s01e01-e02 - Caretaker.m4v

But that doesn't seem to fly, neither does "01-02 - Caretaker.m4v"

Any idea what I'm doing wrong?
