It would be great to allow for multiple SKU's in links that automatically add products to the cart. (e.g. links from this page https://www.netohq.com/support/s/article/automatically-apply-a-discount-with-a-link)
So for example, If I wanted to add multiple products with varying quantities to the cart when a user clicks a link, they could receive a link such as: website.com?sku=myproduct;myotherproduct&qty=1;5
The SKU and QTY parameters could just simply allow for multiple values delimited by a semicolon (or whatever character would be best).
