[mp_list_products] delete excerpt and put a medium picture ?

Hi !

I need some help (again !) to customize the shortcode [mp_list_products]. By default, it show excerpt and a very little picture of my product (cf.capture.jpg). I think it's not really pretty, so I would like show only the title, a medium picture and the price.. I know that we can do that for the default shop page with settings but we can't for shortcodes.

So is there an easy way to do that ?
