Category and how I would lke it

[attroll]

I don’t know if this is possible with this blog software or not, but it does not hurt to ask.

Here is what I would like to be able to do.

I would like each user to be able to create one category under the preset categories that I create. Here is an example of the preset categories I would create.

2007 Appalachian Trail Journals
2006 Appalachian Trail Journals
2005 Appalachian Trail Journals
2004 Appalachian Trail Journals

Is there a way to have it so that I can set up these categories and allow each user to just create one category under each of these I have set up?

To put an even bigger twist on this I would also like users to be able to add sub categories under the one category they can create.

So what I am saying is, I would like users to only be able to add one category under each of my preset categories, but from within the category that they create they can add more sub categories. But they can only add sub categories to the one that they created.

So it would look something like this.

2007 Appalachian Trail Journals
- My 2007 hiker (attroll)
-- My gear list
-- Why I am doing this hike
-- My trail name
-- Mail drops
- Go for the gusto (whiteblaze)
-- My photo gallery
-- About me

I'll see if I can get some options like this worked in, but I can't make any promises as to what version it might be.
