Hi,
I found the answer in another forum (http://listarchives.libreoffice.org/global/users/msg05428.html). It is possible to import the text directly from Word with some of the text defined as Hidden, and then print only what is defined as non-hidden; exactly what I wanted!
Select the relevant text.
-Go to Format | Character… | Font Effects (or right-click | Character… | Font Effects), and tick Hidden.
-Go to Tools | Options… | LibreOffice Writer | Formatting Aids | Display of, and tick “Hidden text”.
-Go to Tools | Options… | LibreOffice Writer | Print | Contents, and ensure that “Hidden text” is not ticked.
The marked text will now be visible in the editing screen but not in Page Preview or printed output or material exported to PDF.
