Currently, it's during voyage creation that the voyage AND containers are created in 1 go.

However, our customer's process is:

1. Shipment booking at forwarder
2. When shipment is done at vendor or subcontractor (for TO's) containerization is done where exact container contents (products, quantities, variants, ...) are registered.

In the landed cost voyage creation process, this is not possible since voyage lines can only be created when container is defined.

Workaround would be:

1. Create shipment + add all lines to dummy container
2. When container content is known: Delete all voyage lines and create new voyage lines with correct containers.
3. Voyage data entities can't be used, since you can't overwrite the container in the line entity (read only)
