Can I use MailMerge and MS Words as Report Generator instead of Access Report?

This is not about coding question. It's about Software (Database) Design.

Background: My office has a ADP database as front and SQL Server is a backend. There are a dozen of basic standard reports in the ADP file. End users slightly change reports every year such as adding some texts, changing logo, bolds, highlights. I help them back and forth for updating these. After they are ok with the report, I upload to the server so other users can use it. I do this over and over over the time (hundreds times). I think there should be a better way.

Recently, I test a new design by splitting Report and Database. I let use开发者_开发知识库r create a words file for the report that they like. I add MailMerge fields in the report after they're done. My users are very good in MS Words. In the database, I add standard MailMerge code. When users pick what template (docx) they want for a report then runs it, it works fine.

Question: Can I use MailMerge and MS Words as Report Generator instead of Access Report? if it's work fine, I will rollout to all the reports. I just want to miss anything before doing so.

Pro(s)
- Users can add any complex format to a report (almost anything you can imagine in MS Words, which you can't do in Access)
- I have less work. No recode, recomplie, or reupload.

Con(s)
- Report Desinger is run faster than MailMerge for a large report.  
- Train user how to update MailMerge fields

Yes, you can use Word and MailMerge to create reports. However, keep in mind that you're giving up control, since users could edit the templates in a way that breaks your MailMerge.
