Custom Contact Ringtone

[Guest Groove60]

Hi all, I recently received a Shadow for a gift and app unlocked my phone and am enjoying the accessibility that it gives you. One thing that has bothered me is that I can't put custom ringtones for texts from a specific person. Is there any program or setting that I can install or tweak so it gives me this option? It has been really helpful as I don't need to look at the phone to know who the text/call is from which makes deciding to pick it up a lot easier! :( Thanks!
