How to change order steps urls

[mtato]

Hello! 

 

I am trying to configure the url's of my prestashop due to some SEO changes, and here comes my problem.

 

I want to change the url of the different order steps (adress confirmation, delivery method...). Right now I have changed it from SEO & URL's to "myprestashop.com/cartprocess" but when I go foward in the order process the url changes to "/cartprocess?step=1" in the second step or even "/cartprocess" again at the 3rd step (I don't know why).

 

I want the url's to be "cartprocess-1", "cartprocess-2"... but I can't really find the way to do it. From SEO & URL's option I can only change the url to be like I have described and I also tried to change the .htaccess file with no results...

 

Some clues on how to do this? I have been told to change something in dispatcher.php file but I don't know what to change there.

 

Thanks in advance and sorry for my english (not main language)
