We need an automated process to create multiple documents with one template.
Imagine a process where Company1 creates an InDesign doc/template. They attach it to a customer account where that customer can upload a CSV file to populate the stories in that doc. Let's say 5 stories
If that CSV had 30 rows with the 5 stories in each row then the InCopy > InDesign functionality would create 30 unique documents with potentially unique content.
