Can jitsi audio-cast from the server?

Is it possible to feed an audio to all the connected clients, that originates from the server? (triggered to start/stop/pause by the moderator, or in the worse case, by some server-side hack (by the server admin))

I have not yet experienced jitsi as either end-user or installed it on the server, but wanted to know if it had such a feature or hack potential (Have only experienced zoom video/audio conferencing, so far, as end-user)

The server-originating audio feed would then, of course, be “mixed in” with the “normal” feeds, from the participants. I am thinking that would result in a more synchronized “viewing” (“hearing”) of the simulcast
