How to make a custom template for data export:
Copy an existing template (such as Template_Default.ods) into the "templates" directory and
rename the template (eg. mytemplate.ods). Open the template file in LibreOffice (version 6.0+),
do the needed customisations and save. Start the WOT client (or use the reload config feature) 
and the customised template will be available.
