Voice prompt and doorbell chime extenders

I’ve been trying to find a way to extend my systems voice prompts and doorbell chimes. During this search I’ve lost count of all the other Simplisafe owners looking for the very same thing. I myself would buy at least 4 of these devices if they existed, why isn’t this in development yet? Requests for a feature/device like this go back several years.

I’ll even ask nicely, pretty please make these units?
