Contact Role

Cay anybody help.
Is there a way to add a "contacts role" field to the process where a prospetc is converted to an account and contact. As it is at present the field refers to what role the contact is playing in the deal process. When converted they becom a contact and I have to re-enter a role within contacts.
I find that by describing what they do at the prospect conversion stage is enough and can be utilised in the contact information. This means I do not need to reenter their role description once they become a full contact.
