multiple WordPress child categories taking parent category name

Hi,

I've just run into something I've never hit before on a WordPress site and would like to get your opinion.

For the site I'm working on, I want a category structure of products > states > [keyword] city. So, something a bit like --

www.widgets.com/red-widgets/washington/red-widgets-seattle/

It's a good structure for the site and a good SEO-friendly silo. However, I've just discovered that if you have a child category that has the same name as another, WordPress goes and adds the parent category to the slug to differentiate it :rolleyes:. So if I have a category like the example above and now add a blue widgets category, with of course Washington as a child category, this now becomes --

www.widgets.com/blue-widgets/washington-blue-widgets/blue-widgets-seattle/

That looks really keyword stuffed to me! I'm sure you guys have run into this before. Has it had any negative impact on you? It looks, as you look at it there in the second example, like pure spam. I've never actually had to design a WP site with this kind of nested category navigation and so have never run into it, although it's kind of ringing one or two bells that I've seen URLs like that before in my travels . Have you been forced by this (bad architecture IMO) WordPress design to use child category slugs like that and did it have a negative SEO impact on your sites that you noticed?

Thanks a lot.
