I think it'll depends on how the brick manufacturer manage it. and how they come to an arrangement into how the bricks are "packaged" to be delivered. It is an interesting idea, as at the brick manufacturing point a lot can be done in terms of pre-packaged. We know for a fact, that what ever FBR has done they have software to calculate which, what bricks gets laid 1st, this can be fed straight to the brick manufacturer before build, and a BLocks package can be manufactured out the back. Doing stuff at the factory level is a lot easier. Also, you save time cutting them within the HX and space/storage. Technically, with pre-loaded blocks, it'll be zero waste.
