I am afraid to have to agree with Dave on this one. Despite the fact that BIAB claims it can utilize all these arrangement shortcuts (See figure below) I personally have never been able to make it work. In the early days I tried hard since I worked alot with fakebook arrangements similar to what you showed, but alas it was beyond my pay grade. I just accepted that the linear arrangement was the way to make it happen. But good luck to you I admire your efforts. Perhaps one day someone will come along to show us all the way.
