Does anyone know of an app that allows you to assign a ringtone/notification to specific apps? I have an app (Amazon Seller) that has its own notification sound that can't be changed. I can only turn off notifications which I don't ant to do. I am a large Amazon seller and the thing goes off none stop, and the notification sound is driving me nuts and its LOUD and annoying. I have searched and search and have had no luck find an app (found 2 that don't work worth a crap). Please help me keep my sanity. Thanks
