Subtemplates
Subtemplates can be used to make common pages like a certification or a definitions page available to call into a report.
The template being called first needs to be set as an attachment on the subject.
The subtemplate can be called into an existing template using { MERGEFIELD “Your Subtemplate Name.docx” \Exhibit }.
It is important to note that there needs to be at least one other actual mergefield in the template or the subtemplate won't show.
