B2B ecommerce - ability to choose shipping date at the time of order checkout

We would like to have one functionality in the B2B e-commerce website at order checkout, where the customer can choose the requested ship date. This field value should be mapped to the D365FO Sales order header field – requested shipping date. Currently, it is by default mapped to the order creation date.

Reason for an idea – Our customer wants to place future orders from B2B e-commerce website.
