I don't see that type of url structure as traditional but rather as antiquated. Way back in the day when I was building websites using notepad, an ftp account and a Unix server, we did things that way to we wouldn't have to use the .html at the end of our urls. www.mysite.com/about-us would bring up the index.html document that was stored in the about-us directory.
This type of url structure has long since been dropped by the majority of the web and for good reason. It doesn't provide any additional value to the user now that we have things like extensionless urls. Also, SEO isn't improved by using a "directory" structure to urls. In fact, it is very easy to get carried away with that kind of thing.
So many other CMS platform put all kinds of sillyness in their urls making the resulting link so hard to remember that we needed url shortening services to create new tiny urls that have no basis on what is actually on the page.
Anyway, I'm not sure of a solution that will help you do this and I'm not sure you would be any better off doing it.
