Voicemail folders


When you recieve a voicemail you have an option that allows you to move the message to a folder, e.g., Work, Family, etc. I want to know if it is possible to delete this option, I mean, that there would be only a folder and you can't move you voicemail messges. If it is possible, it also delete the option when the IVR ask you which folder you want to hear?

Thank you very much
