Use custom word templates - mattias-skold/EnhancedExportDocumentation GitHub Wiki

Once you have created a custom word template you can now export your data to it.

Exporting

To open your export with your custom word template, simple go to the export tab and drop down the Open menu. All available templates will show up in the list and you can choose your template.

This setting will persist - unless the report template has a default custom template defined.
