Allow Preorder option for B2B site

Hello,

I would like to suggest the ability to Preorder products on the B2B site. If you could select a “preorder” option on a per product basis and allow customers to place orders based on the incoming stock to ensure there are orders for products before they arrive. It would be very helpful so customers would know what is coming in and if they want the product they would have an order they placed already be in our system. Ideally, for example, if a product had 160 units incoming for the month of April then the preorder option would only take orders up to 160 then the product would be “sold out”. Then once they product arrives, you would switch in the product page back to order and then customers could place orders like they already do on the B2B page for available stock left over. This would not only increase sales but would be incredible knowledge on what products to order more of or project for the next year.
