Door ajar alerts

Please add door ajar alerts so you can select go have door sensors alert if a door is left open for more than a certain period of time.

Can the base station play a constant sound until the door is closed? Example - kid left door open. After 1 min of remaining open, play siren sound on base station (different than alarm siren) and send push notification

This will ensure that the door keeps getting closed and my alarm can be armed automatically anytime my door is closed via Alexa.
