Motorola Droid X :: Way To Set Text Message Notification Sound?

On my old phone (LG Dare) the phone would beep every x number of minutes if you did not read a new text message. Is there a way to set it up on the DX so that if i don't read a new text after the initial ring, it will beep or play the rington like every minute. this is the only feature i miss, bc sumtimes i walk away from my phone and miss the text coming in and i wont know its there unless i check my phone. I would like to have it beep or something every minute as a reminder that you have a text waiting.
