Add cover page to mail merged document (Writer)

Add cover page to mail merged document (Writer)

I need to generate a single document from multiple CRM records, so I do a mail merge with a Writer template.

Is there any way to automatically give this document a cover page? If you include the cover page in the template, it will of course be repeated for all CRM records. But this is a single document with multiple records, it needs only one cover. Something like this:

Cover page
CRM merged record 1
CRM merged record 2
CRM merged record 3
Etc.

The merged records have one or several pages each, they are not rows in a list.

Is there any way to automate this, or we must add the cover page manually? It becomes a bit tedious when you have to generate ten documents like this in a row.

Thanks!
