Selecting a delivery date before checkout

Hi everyone,

My website is and we would like our users to be able to select their delivery dates before hitting the checkout screen. We currently deliver once a week and would like to move to two pretty soon. As of now our customers see this orange highlight bar indicating the delivery date for their order on every page,

but we would like to give them the ability to select a date via a drop-down and have items reflect the availability for that specific date across the website. Has anyone come across a use case like this?

We’re currently using for our checkout flow and would only need the cms items to reflect the delivery date availability. Any advice would help!
