Gets ors sets whether headers (footers) in the merged document have the same content in all sections.
true, to link headers (footers) one to another so that they have the same content; otherwise, false.
In the mail merge technique, if the MergeMode.NewSection option is set to true, each data record results in a new section being appended to the merged document. If the HeaderFooterLinkToPrevious is true (by default) , the header or footer in a new section is linked to the previous one, so they have the same content. If you set the HeaderFooterLinkToPrevious option to false, you can specify the content for a section’s header or footer independently.
