Banners Between Forums and Topic Headers On Index and Forumdisplay

[ldma]

I've had a little hunt but can't find anything that does this specifically, though I've seen it done for posts.

How about a mod that allows you to set-up banners in the middle of forum and topic lists, in effect splitting the list of forums on the index page and splitting the list of sub-forums and/or topic headers on forumdisplay? Perhaps you can specify a number of these splits as after the first 3 and then the next 5, or by after every 3 for example.
