Is there a way to add autoresponses? For example, under an event the options are "RSVP confirmation to guest", "Event confirmation to owner", "New RSVP to owner", "Canceled RSVP to owner". Can I add a fifth autoresponse? There are other reasons to send an autoresponse and it would be helpful to modify them as those reasons come and go. I.E: Event reminder (X time beforehand).
