Is there any way to make reminders selective?

EX: I have an appointment to see a doctor on Monday, I also have written work due Monday (as I do on most days)

My problem: I want to get a reminder (via SMS) on things such as appointments, birthdays, dates... etc

I do not want to get reminders (via SMS) about daily work load, such as papers and readings due.

Is there any way to make reminders selective, or is it all or nothing?
