Can I email Harvard admissions about a change in my schedule?

I applied SCEA to Harvard, and I just guessed which post-secondary course I’d be taking second semester, but now that I’ve actually set my spring schedule, it turns out I’m going to be in a 4000-level course rather than a 2000-level course. I realize that this change will likely have zero influence on my admittance, but I’d like to email them to make the correction anyway. Is this something that people do or would it be weird/annoying?
