Prepend Message to Broadcast

Is there an easy way to pre-pend a message identifier to any broadcast messages at the server level? For example pre-pend the phrase “[GROUP:]” to the message.

(I.E.) A user sends a broadcast message via the broadcast plugin from their client, and all users in that broadcast group receive the message, but the Jive Server or plugin has pre-pended a message, like “[GROUP:]”, to allow users to understand that the message was sent to their group.

If someone uses the broadcast feature to contact me, I’'m not sure of the message is directly intended for me or my group.
