Conference Pro IVR exit option?

I’d like to give my users the option to exit the Conference Pro IVR, like “dial 0 to reach an operator” like in regular IVRs.
Currently the Conference Pro IVR only give the option to dial conference call numbers and that’s it.

How can I add an option to dial one additional destination?

At this time you can not. Please open a feature request at issues.freepbx.org
