Ignore bluetooth mic

Thanks for your work. Could you include an option to ignore the microphone of the connected Bluetooth device? as the option of the headset. The reason is that many car stereo bluetooth devices have poor microphones and it would be better to use the phone mic.

Thanks

The Android Policy manager will not allow a Bluetooth phone call to utilize audio output and audio input from different sources. If a Bluetooth device is used for phone call audio, then it must also have an audio input (microphone).
