New Button Interaction - Update Product Selected, Allows 1 PDP With Different SKUS

Hi I’ve ran into this a couple times. Clients have multiple skus for inventory purposes but they are truly one product. In some cases, snacks with different flavors created as products instead of variants. For example, Replo allows you to update product selected in buy box. The alternative in Instant is having to code this in js and update the product/variantID and then conditionally show 3 separate buy boxes based on product selected.
