Historic audit trail for reports

What is the challenge?

Currently we are not able to track any changes made to reports via other user.

What is the impact?

Whenever there is a change to a report values or filters we are not able to track the changes. This becomes difficult to track and understand why the change was made.

Describe your idea

The idea here is to give a functionality to track any changes made by the users to the reports so that we are able to track the changes effectively.
