I have a Droid 3 and I only use one calendar; but when events are back to back or close together, it would be nice if each event notification could be set separately to a different ringtone. From what I found, different notifications/alerts are set BY app . . . but hopefully WITHIN one app (the calendar), each event could be assigned a separate ringtone, similar to setting separate ringtones each of your contacts/callers. Is this possible in the calendar and I just haven't found it????
