How to make "Subforums" not show on top level, shown on all others?

[Sonno]

Hello all, here's something that's been buggin me.

I have my Forum Listings Display Options set to:
Depth of Forums - Forum Home: 2
Depth of Forums - Forum Display: 2
Depth of Sub-Forums: 2

It's the "Depth of Sub-Forums" that's getting to me. I want to see the subforum listing under the category lisyings on every depth down except the very top. How do I go about doing this?

If you can't understand what I mean, tell me and I'll photochop a pic to better explain what I'm talking about.

Thanks!
