Full MIDI Score

Is it possible to create a button near the arrangement that when clicked would open a window in full screen that would sum up all of the MIDI parts of separate chaels in one full score? This way you have a nice overview of the whole composition with all the elements and when you edit in that score the information would also be change in the individual midi parts of the elements and vice versa. I think this would change the game on how we look at orchestration and composition and would make the whole process a lot easier. Thank You.
