Make fields tie together or autofill from one module to another other than lead to customer

Could you guys make possible to enter info in a field on a potential and have it update to that same field under the contact that the potential is tied to.  For example can you make a way to map dependent fields outside of lead to contact. Or allow for an automated workflow that will allow me to have a phone number or email address that is entered into a potential copy to that same field under the contact it is related to.
