Does anyone have a solution to create future orders in Shopify?

Hello, I have a stand alone wholesale store set up and am using Shopify to both take and input orders manually.

I am in need of a way to put in future orders as I get customers who order perhaps 4 times at once for months later. I am hoping to find a solution that would let me put a shipping date on the order manually and Shopify would sort by the date.

Any ideas?
