tstrebeck on "Display menu for pages under specific directory"

Here's the basic structure of my site:

Section 1
- subpage
- - sub subpage
- - sub subpage
- subpage
- - sub subpage
- subpage

Section 2
- subpage
- - sub subpage
- - sub subpage
- subpage
- subpage
- - sub subpage
- - sub subpage

Section 3
- subpage
- - sub subpage
- - sub subpage
- subpage
- subpage

What I'm wanting to do is display is the first level of children of each section at the top level of that specific directory and for all the children underneath it. Is there some way to accomplish this? Will I need to create 3 different menus and then set up some sort of if/then scenario?

Thanks for your help!
