There is a feature today called Future Orders in the call center functionalities (see details here https://community.dynamics.com/blogs/post/?postid=f8b28e3b-814f-4eaa-8555-66baabb7c8cb). Currently this feature will only work at the header level (applies to all sales lines). Therefore, a whole order is identified as a future order or not, and you must manage the payment authorizations at the order total level. To make this more flexible it should be possible to evaluate future orders at the sales line level, so the system can treat a specific sales line as a future order and not trigger a payment auth for that specific sales line with a future delivery date.
