Ring Video Doorbell 2 Motion Warning

I have the Ring Video Doorbell 2. When I opened the settings today, I noticed a new feature labeled Motion Warning. However, when I try to turn this feature on, I receive a message stating “This Ring device doesn’t support motion warning.” My question is, can this feature be added to the lower model ring devices? This feature works great on my spotlight camera and I would love to see it added to my video doorbell.
