The best that I can tell is maybe you can schedule one tone for day and one for night. You could even change the tones each day. Hope that helps.

right now i think that is only for verizons ringback tones. it took them a year after it's launch to put that feature on, so who knows when cingy will do it. there is, i believe, a day and night setting so you can have different tones depending on the time of day.
