Webflow Ecommerce - How would YOU make this?

I thought I would be able to create a color field to feature a swatch and more just like Webflow CMS. Also, I am stumped on how to create a quantity selector and add all to cart button. It seems webflow doesn’t have these features ready yet. Is there any work-around that you know of? Why can’t we make custom fields so that we can design product pages and lists like CMS items?

Knowing what I would like to build, how would you attempt a work-around?
