Changing info for Contacts on Account page

Changing info for Contacts on Account page

On an Account page, the Contacts for that Account are listed.  But is there a way to change the data that is shown?  For example, on my Account pages, under Contacts there is the Contact Name, Email, Phone, Mobile and Fax.  I'd like to remove the Fax column and I really need to add a Title column, which is included on the Contact's page.

How can I do this?

Thank you!
