Allow joining 2+ Chimes in App with single Video Doorbell for extended Chime coverage

Not a second Chime Pro, no, but last year they introduced Duo Cam Doorbell with Wi-Fi Chime, and earlier this year they began selling the accessory as Universal Wi-Fi Chime. As far as I know, Wi-Fi Chime would be the only way (currently) to add a second (or third, or fourth…) chime to an existing Video Doorbell Pro.
