Adding columns to Business Contacts Address List

We are implementing Business Contact Manager with a shared database in our
company.

We want all users to access the Business Contact Manager Business Contacts
list as their address book when sending emails.

I want to add additional columns in the display for the Business Contacts
Address List, specifically the "Company Name" that is entered for part of the
info for each contact.

Currently, the Business Contacts Address List only shows 3 columns: Name,
Display Name, and Email Address.

We are moving over from ACT! and this program allows searching of addresses
using such things as company name.

Is there a way I can add do this in Business Contact Manager Contacts
address list? Thanks in advance for any help!!
