Flatten View For A Specific Directory (no replies)

You know the "Make it flat" option on the widgets (Pages for example)? Ok, so that is really neat, but I need something a little more specific. I need a "flat" view for specific directories, but without separating those directories from the rest of the site. Let me try to provide an example.
My site is www.mysite.com

I have some directories like:
www.mysite.com/Org1
www.mysite.com/Org2

Those directories might even have other folders/directories, like:

www.mysite.com/Org1/Dept1
www.mysite.com/Org1/Dept2
www.mysite.com/Org2/Dept3
www.mysite.com/Org2/Dept4

And sometimes, those sub-directories might have folders and more within them. At this level it would be for images, files, etc...

What I need is to be able to have the "flat" view for let's say "Org1", as well as in the "Dept2" directory independently. But I still need to have the capability of viewing the entire site as I currently can in either hierarchical or flat view.

My point behind this is I have a site with different departments of our orginization having their own directory, and some of those departments are within a specific "Organization" of the company. And I need to be able to see the top views for each organization, and department, as well as the site as a whole.

I have been researching, testing, and reading as much as I can and I have yet to find it. I'm sure it's out there and I am just overlooking it. Could someone please point me in the right direction? Either an API, plugin, or whatever is fine. I can use any, just need to know which one and how. I have played with the API's some, but I am yet to be able to figure out how to make it do what I need it to do.

I hope this all makes sense. Thanks!
