I finally found a method book that doesn't mess up instrument assignments. Essential Technique for band. I can assign ONE excerpt for the WHOLE band to work on without it showing up available for a small section like the Tradition of Excellence series. That being said, my students have the physical copies of the tradition of excellence series and it would be nice to be able to assign them pieces from there without having to figure out if the "Bb scale" is going to include their instrument or not. Seriously a stupid design flaw.
