For PDPs, buy box component should have a variant 'list' listed by number vs variant names...

The idea is that if you have a PDP with a bunch of products assigned to it and you want to display “X” certain product variants, then you should be able to set ‘variant order’ so the ‘selected variant’ is always the number #3 on the list, and apply the same for all the products. Having this in mind products will be created with that specific variant number/order in mind.
