Better workflow for producing multiple documents with the same content.

Hi, there guys.

I have a bit of a question which someone might have a solution/s.

Every month I am producing multiple reports (30) made specifically for different clients but the content commentary (description) are almost the same. I make the initially report with the content (with words and charts) then that same description goes to the rest of the report.

All the reports are templated the same for all (2 columns with Paragraph and Character Styles).

My challenge is how to "improve" my workflow when revising the report. Because when the main report changes, all the reports change as well.

Internally, we made sure the initial report is checked until it is absolutely correct. But there are times that there are last minute changes and that means I have to manually change everything.

When that happens, I do Find/Change on All Documents then export as pdf.

Initially, I thought of using linked Indesign Story and the edits will be done with InCopy and using a script to export all pdfs at once to cut the workflow process.

It's an interesting challenge but hoping someone has an answer.

Much oblige.
