App to enable answering calls with bluetooth auto-enabled?

[MichaelBanning]

Hello! I've tried searching the forums for related posts with little luck. When driving either with or without driving mode enabled but when the phone is still connected to my car's bluetooth device, I would REALLY like to be able to answer calls and have the bluetooth option automatically enabled without having to try and hit that small bluetooth button while driving, but I can't find a way to do that. Is there any app out there, or does anyone know if someone is working on an app, that will allow me to do this?

Thanks for any help!!!
