Linking devices across home bases

Hi,
I’m wondering it if it’s possible now (or if it will ever be possible) to connect devices across two homebases in the automations menu.

Currently we have a Homebase connected to our security cameras and we recently added a doorbell connected to a chime.

Ideally what I’m hoping is to be able to sound the chime alert (so they can be heard from different rooms) when someone rings the doorbell (on both Homebases rather than just the chime device) and set of alarms on both rather than just on one.

Do I have any options at the moment?

Thanks so much in advance!

Won’t work with existing Homebases because they only talk to child devices and the app. They don’t have a way to communicate with each other. Eufy doesn’t seem interested in providing a solution to the issue.
