Currently, after completing a data merge, the generated document loses its link to the source Excel/CSV file, making it impossible to update content (like product names or prices) without re-running the entire merge. This becomes a major issue when we've manually added custom pages, layout tweaks, image adjustments, or element placements based on text length—re-merging resets everything.

Suggestion:
Introduce a "Dynamic Merge" option in the Data Merge panel that maintains live links to the CSV/Excel source. This way, users can choose between a static or dynamic output. With dynamic mode, merged fields remain linked and identifiable, allowing easy content updates from the original data file without losing layout changes.

This would save huge amounts of time and prevent repetitive layout work.

Thanks!
