Enable Motion Notifications by Mode

Please allow the setting of Motion Notifications by mode.
I currently have a schedule set to only recieve Motion Notifications at night. What I’d like to do is have the ability to override this and recieve notifications based on Mode.
For example, when leaving the house I would like to set to Away mode and recieve motion notifications when I am out of the house.
I really can’t understand why this isn’t already a function, feels like it would be easy to do as you can select motion capture in this way already and it would be incredibly useful. Thanks
