Assigning ONE Notification to (All) Text Messages and Nothing Else

[monicakm]

Is there a way to assign a notification sound to text messages without that same sound being assigned to other notifications? I'm not talking about assigning a sound to an individual's texts, just text in general. I can't figure out how to do it. ALL notifications sound the same. Surely it can be done. I've tried with the phone's default sounds and Zedge.
Thanks
