[Plugin: WP Easy Post Types] Rewrite custom post type slug

Hello,

First sorry for my bad english.

I would know how can i rewrite the custom post type slug, because i can’t change the system key..? My system key is “articles_img”, so i have urls like “http://www.test.com/articles_img/mypost/”, and i would have “http://www.test.com/news/mypost/”… Is it possible without create a new post type ?

Thanks !
