Export to Word (rather than just PDF)

As good as the document builder is, we really need it export merged documents into Word rather than just PDFs. Headers and footers, margins and page breaks are all issues at the moment but an export to Word function would resolve everything. At the moment we are having to merge the document in Document Builder then cut and paste it into a separate Word template with the correct margins, headers and footers and then convert it back to a PDF once it ready.
