Catalog Collections (CMS) (new Feature)

I’m having trouble with
Catalog CMS Collections (New feature!)

Working in
Wix Studio Editor, Wix Editor, Dev Mode, CMS

Does anyone know about ‘Catalog Collections’?

1- Automatic discounts and coupons: are Catalog Collection items eligible for discounts when added to the cart or checkout?

2- How to do an advanced linking of adding to cart using the add to cart and createCheckout API/Velo, regarding the functionality of adding the item to the cart, or to the checkout, along with a dataset?

3- I know it’s still a new feature, but does anyone know or have been informed that it’s a feature that will be improved in the future?
