So is there anyway someone can write a patch that will allow you to map the voicemail button in the phone app to a custom number? I would love to map it to my Google Voice number, but to this point I have not found a way to do so. I even changed the "Voicemail" contact in the phone to my Google Voice number, but still the button just calls my VZW number to access its voicemail.

Small thing, but something that would be nice.
