Possible to use TM's load optimization -without- an order?

We have multiple use-cases for load optimization – the actual planning of pieces within the equipment – whether it be 20’, 40’ Container, 53’ truck, etc. We know that the TM-encapsulated solution works on the back end once we have an order, but we have use-cases before we have an actual order: Customers / internal resources would use the solution to plan and create an order based on the results of the container optimization: IE, if I’m ordering a container direct from China, I want to submit my order for exactly how much of each product will fit on the container.

Is it possible to use load optimization for cases like this?
