Develop a mechanism to be able to change questions, answers and scores

[ruslanbaidan]

We need to develop the feature to be able to add, remove questions and related answers, and change scores of the answers without impacting the previous surveys' results.
One of the ideas is to create a versioning of the questions, answers and scores. and in order to get the right results version or date filter to fetch the right data.

It is currently possible to change questions, answers and recommendations by modifying json data and reimporting them.
However there is no history tracking of the changes.
The removed questions and answers status will be set to inactive.
