Smart Alerts - two different motion zone settings

I love the new Smart Alerts feature, where I can have Ring Cam record all the time, but only send me a notification if it detects a person.
Right now, the Motion Zones I set seem to be used for both people-based motion and non-people-based motion detection. What I’d like is to set the Motion Zone to the entire video frame for non-people-based motion. And then only select a portion of the video frame for people detection.
