Custom Fields in Dashboard Widgets

Hi all,

I was wondering if someone could explain to me the procedure to have a custom field show up in the dashboard widgets (10 highest priority tickets I own & 10 newest unowned tickets specifically) or point me in the direction of the appropriate documentation? We use a custom field to keep track of the customer making the request for billing purposes as well as using it as a unofficial knowledge base of what has been done (by whom) at a customer site and how an issue was resolved. Thanks.
