In order to correctly handle multivalued responses to questions contained in the medallia api json response, a new column needs to be added to the feedback_answer table that contains the ordinal rank of each response to a question when the response is multivalued. This is because some medallia multivalued responses are intended to capture a rank-order. 

Consider a question like: 

Rank your favorite Bluey Characters:

1. Bluey

2. Bingo

3. Chili

4. Bandit

5. Snickers

If the json response payload contains [3, 4, 1, 2, 5] then storing these without order does not allow end users to correctly interpret the results.

If instead we store:

Response | Order

1               | 3

2               | 4

3               | 1

etc.

Then we can correctly understand the response.
