I have a couple of wordpress urls that I want to simplify for SEO purposes. I have 
<http://www.example.com/fr/product-fr/review-fr/>

I would like to change that to <http://www.example.com/fr/product/review/> (remove -fr) but without changing the URL internally. So the user would access <http://www.example.com/fr/product/review/> but the server would serve the content of <http://www.example.com/fr/product-fr/review-fr/>.

I want to do this to get around a URL problem with Wordpress and WPML.

Appreciate the help
