Is it Okay to Omit NHS on Common App?

Hello,

So I’m getting ready to turn in EA applications to Yale, UVA, and UMass, and I have a conundrum. I don’t have NHS anywhere on my common app because I have other awards/ecs that I consider more important to my application. I don’t want to make a resume to add it in because I don’t have tons of other stuff to include on the resume and I don’t want it to be just reiterating what is already on the common app. So, is it okay to omit NHS? I don’t really do much for it at my school, just attend monthly meetings and do some community service. Will these schools assume I’m not on it if it’s not there?
Thanks!

You can add a note in additional info if you want to. It works not hurt to do so if you are out of space in you EC list.
