I'd love a way to copy the Category/forum/sub-forum structure/permissions to another

[rnmcd]

I'd love a way to copy the Category/forum/sub-forum structure/permissions to another Category in the same board.

Lets say I have a deep Category/forum 'path'. For example, the Main Category has three sub-categories, and each of those has 4 sub Categories, and each of those has three forums.

I'm looking for a mod that will make it possible to copy that structure/prermissions to another category. Then I can just edit the Main Category Name and retain the naming and permissions of the sub-categories without adding new categories and sub, sub-categories manually.

Thanks!!!!
