Different forum depth per forum/category

[jmfemedia]

As the title says, I am after a way of making each forum/category have it's own forum depth instead of using the global forum depth that is set in the vBulletin Options in the ACP.

So far my forum has been fine using the global settings of home - 2, forum - 1, subforum -1. But today I needed to create a "forum within a forum" that requred a setting of 2/2/1 which then totally messed up the rest of the forums. All I need is for that one area to be 2/2/1 and the rest can keep the forum default.

I've tried, exhaustively, to find a mod or a template change or code change to do this but the closest I have found is for a majorly old version of vB from back in 2001.

Any help is much appreciated.
