Change class names

Hi
Thanks for this plugin, its amazing and solves a lot of issues with my site.

One problem I have is I am using the shortcode a lot for different pages to show posts from specific categories. I want to style the posts it generates out but theyre all under the same class name.

Is there a way to specify the class list in the short code? at the moment theyre all under the listing-item class.

Many thanks
