How do I get my band director to choose me for section leader?

I’m a rising junior and I REALLY want to be section leader my senior year. I have a very good shot at it, too. I’m the best flute player of my year (even though I’ll be playing piccolo) and by my senior year I will have marched all 4 years. I’m a pretty good marcher, although last year I was definitely not. I improved a lot in general last year. How do I get my band director to notice me? I want to show them that I would be a good section leader, but I’m not really sure how to do that without overstepping my bounds.
