Voicemail from queue identification

I have two queues that have a shared voice mailbox; the problem is when staff listens to the voice mail they do not know which queue it came from.

One idea I had was to send it to its own voicemail box, run sox to append a short message from queue x then copy voicemail back to another the shared voice mailbox.

Any thoughts to what can be done?

My only idea would be to use different Voicemail inboxes for different Queues.
