Changing modes changes doorbell smart response

It would be really handy if when arming the system, it automatically changed the smart response on the doorbell to one of the choices which state to leave a message. That way the doorbell acts as an answering machine when the house is empty. Of course coming home and disarming the system would return the doorbell back to what it was set to previously. It would also save having to manually change the smart response message on leaving the house, and back again when returning.
