Broadcasting custom messages to different breakout rooms

After searching through the zoom documentation and past forum posts, I believe that there is still no way for meeting host to send broadcast messages to the zoom meeting through API (? - please correct me if I am wrong.)

The feature that I would like to see is to be able to send a customized broadcast or welcome message that is different for each breakout room.

For example, a person joining breakout room “Team A” will receive the message in the meeting chat “Welcome to Team A.”

Is there any way I can go about implementing this feature or are there any alternatives that I can use to achieve a similar result?
