Can the resume elaborate on topics already discussed in the Activities Section?

I understand that many colleges will use the activities section of the Common App almost like a resume to see what you have been doing in high school. However, when some colleges ask for an optional resume, would it be appropriate to elaborate on those activities? For example, on the Common App, I listed an orchestra that I’m heavily involved with as one of my activities. However, besides that orchestra, I’m involved in my school’s chamber orchestra and my state’s regional orchestra. They are all meaningful to me but I don’t have enough space to have each of those activities have its own spot in the activities section. Thanks!
