That is fine, but I think you will find that when you do that you will still get a 3.
I have not ever really seen a band that has components of the band be at a 1 level and the overall band is at a 3. If the band is a 3, the components are probably a 3 or 2 at best
While UIL has rules and requirements about marching, the audience comes to hear the band not necessarily watch them march. Music is the most important part of the contest.
