Send user to modify specific recording?

I have users that only call in from regular phones. I’d like to be able to let them change their IVR messages without having to do it manually. I’d send them directly from an IVR into the recording AGI for a specific message (the message for their IVR; think *77 / *99). Would it be very difficult to hack that sort of thing?

should be pretty easy, just upgrade to 2.5 - it’s already been implemented:-)

Awesome (I’m already on 2.5)!
How exactly do I set a destination to edit a specific recording?
I see where I can make *77 a destination in misc destinations
but not how I can set the message name?
