Email page layout

Is there a way to edit the page layout for emails sent to candidates? We want to make the Requisition field required, or at least add static text with instructions, but I don't see a page layout available for customization. It's possible to send emails with no requisition selected, and with merge fields from the requisition included in the templates, the emails go out with values from a default/random req filled in. Obviously that makes us look really bad and is not a good experience for the candidate.
