How to make a specific ringtone, email, sms/text, notification for a contact?

I know there is a thread on it but I have to ask.. Is it possible to setup different sms tones for different people?

When I setup my daughters NEW profile, then tone, then new exception her sms tone will come up...

THEN

I did the same fr my wife..... she texted me and her tone came up...

so far so good

Well then when my daughter texted me again, my wifes tone came up instead...The only thing I can figure out is that the last tone that I set, became the new tone...

There has to be a way to set the bb up that each person has their distinctive sms tone...

Help/suggestions

I have the same need, anyone have an answer yet?
