Stack vertically before horizontally

[UdoW]

I have following example:

Container container = Container.newBuilder().withDescription("1").withSize(12, 3, 3).withEmptyWeight(1)
   .withMaxLoadWeight(100).build();
   
LargestAreaFitFirstPackager packager = LargestAreaFitFirstPackager.newBuilder()
   .withContainers(Arrays.asList(container)).build();

List<StackableItem> products = new ArrayList<StackableItem>();

products.add(new StackableItem(
     Box.newBuilder().withId("Foot").withSize(1, 4, 1).withRotate2D().withWeight(5).build(), 9));

Container match = packager.pack(products);

Here my question:

When I run above code then all 9 items are placed on the lowest level (0) so that 2/3 of the height is empty. I want them to be placed on top of each other so that 2/3 of the area is empty.
The items are forbidden to be rotated in 3D. Only 2D is allowed.

How could I force the packer to stack the items first and then place them next to each other?

This is currently not supported. The problem resembles #150 .

For brute force packager: Can be implemented as "try all combinations" and take the one with the preferred profile.
