Students that meet on a certain day option

It would be awesome to be able to select only students on a certain like classes for emails and text (and parents too).

We have multiple seasons one running at the same time that we use (Ex: Tech classes and competition rehearsals are two season vs. all in one). Therefore if we have dancers on a certain day that is only there for one of the season we have to send 2 separate communications, which is fine but is a duplicate for some. Does this make sense?

Thanks!
