WordPress CPT UI - Change the URL Slug of the Post Type

I had to install the plugin CPT UI (Custom Post Type UI) in my wordpress, then I create a new Post Type named Collectie, so when I opened the post Retro that I publish on this Collectie its URL will be (http://ift.tt/1WRzwj3), then I made a new Post Type again with the name Product, then I publish a post Dressoir on this Product, so the URL will be like (http://ift.tt/22rMAvN) , but I wanted when I opened the post Dressoir its URL is (http://ift.tt/1WRzYOi), how to do that ?
