Linking two docx

Hi
i try to add a header to my template. Header is locate in a another directory. So is it possible to link my template whith my header.docx?
Thanks

You can try by replacing the sub-file corresponding to the header with the one in "header.docx".

OpenTBS can help you to do that:

Unfortunately mixing two DOCX is not really working because of all linked information in each DOCX.
