Adding columns to Employee Packets section on Employee page layout

Content (please ensure you mask any confidential information):

We'd like to add a column to the Employee Packets section on the Employee page layouts, but see no way to edit the section--we see there's a placeholder on the page layouts but we can't do anything to it. Are we missing something? Specifically we'd like to add the date the packets were created.
