DTMF ringtone?

[berrysmith]

With a phone I had a few years ago, I had a ringtone that was a single beep. It was unobtrusive but able to get my attention. With a BB Tour I just got rid of, I didn't have the single beep option but managed to take a tone (the tone you hear when a number on your keypad is pressed) from a dtmf generator and use it as a ringtone. Does anyone know whether I can do the same with my Motorola Electrify, and if so, how? Thanks.
