I'm interested in adding a "more styles" or "more colors" flag (similar to the "sale" flag you can toggle on for sale items) onto specific product thumbs, so that customers know there are variants behind each listing without having to click into the product detail or quickview. Is there a way to do this? 

I think you can assign tag to the product and use css to display the badge
