Spark notifications need to be more customizable

The Spark watch is for my 7 yr old child. But because I have to set it up through my phone and app, it is either sending every call and notification or none. I only need it to give the in app notifications like practice reminder! Spark needs a lot more work, not just using the core settings for a smaller size.
