Send sound to remote speaker(s)

I am new to homey.
I searched the community and internet to find any reference to this but nothing.

It would be nice to be able to send speech or soundboard files to a specific remote wireless speaker.
This could become an

  1. Announcement system
  2. PA System
  3. Lunch bell system
  4. Alarm system

From what I can see this functionality is not available yet.
Is there a road map for the homey software to support this at some time?
Is this functionality that needs to be added by homey or third party speaker developers?

Again apologize if this has been covered somewhere that I missed.

This is possible with the Sonos app and the sounboard app me guess?
