Category Carousel

I have 4.11.1 installed. My client wanted product filters to show on the Brands page. I didn't see this functionality and didn't find an addon.

So I had the idea to make categories that matched the brands, now I have the filters. However I need a carousel on the homepage for these categories. There is a built-in carousel for the brands, why wouldn't there be a display option for categories that does this?

This seems like it should be an easy thing to accomplish, does anyone know how?

I was hoping to not make default banners because I would have to make and remove banners anytime a brand is added or removed...
