Answer doorbell from smartwatch or bluetooth headset

I don’t know if this has already been asked for, but it would be great if i could answer the doorbell with my bluetooth headset or smartwatch, just like answering a phone call or other voice call. Sometimes, i just can not take the phone in the hand, because i am driving or running. And being able to immediately response through the headset, it also skips a few steps of reaching for your phone, unlocking it and open the notification.
