Choosing where 'Sub-Forums' appear?

[grhawkins]

I'd like to have my sub-forums appear on the home page only for the main forums I choose. For example, I want sub-forums to appear for my Events forum, but not my Radio Shows forum (Screenshot: http://screencast.com/t/ppbXeM2efK).

Additionally, how can I only choose specific sub-forums to appear? I only want 4 of the sub-forums to appear under Radio Shows and not EVERY sub-forum under the main forum to show up.

EDIT: Here is my current set-up for the 'Forum Listing Display Options'

Thanks in advanced!
