Can I edit the information seen when viewing a student or volunteer?

I added several fields:  T-Shirt size, T-shirt Received and Paid.  I would like to be able to see the T-Shirt Size without having to select a volunteer and then click the edit button.  When you first select a volunteer, there is some data that appears on the page (like contact phone, email, age group preferred, etc.).  Is it possible to customize this page so that I can see the fields of mine that I would like to view on this page?
