? About navigation/levels

Greetings –
I see the three behavior levels that are listed in the drop-down of the player template under navigation. I'm guessing that since the behavior I want isn't listed, it's not an option. But, I thought I'd check, or see if someone knew a crafty workaround. (My particular application this time is not a course, but what I might call a reference tool. So it's important that people can jump exactly to what they need right at the beginning. I realize that I can instruct them to expand all the levels before they do anything else, but that's annoying   )

What I would like to have happen is to have the entire outline in its expanded form right when the presentation opens. Any chance that there is a way to do this? I don't want to put everything as a level I topic either. I have three main portions of the presentation, and each one has subtopics.

Many thanks,
Janet
