You can probably achieve what you're after with a combination of Word's Catalogue/Directory Mailmerge facility (the terminology depends on the Word version) and/or the use of DATABASE fields. To see how to use Word's Catalogue/Directory Mailmerge facility with any mailmerge data source supported by Word, check out my Microsoft Word Catalogue/Directory Mailmerge Tutorial at:
https://www.msofficeforums.com/mail-...-tutorial.html
or:
http://www.gmayor.com/Zips/Catalogue%20Mailmerge.zip
The tutorial covers everything from list creation to the insertion & calculation of values in multi-record tables in letters. Do read the tutorial before trying to use the mailmerge document included with it.
Depending on what you're trying to achieve, the field coding for this can be complex. However, since the tutorial document includes working field codes for all of its examples, most of the hard work has already been done for you - you should be able to do little more than copy/paste the relevant field codes into your own mailmerge main document, substitute/insert your own field names and adjust the formatting to get the results you desire. For some worked examples, see the attachments to the posts at:
