[IT Collect] - CIO authority data

The "issue" is about CIO authority but it is also a general question about historical data.
Does GSA want to, need to, or have an expectation to see some of the data historically?
As an example:
CIO data will have a rating. This rating of a Service may change for each submission or it may stay the same.
1st submission: the rating may be a 3
2nd submission the rating may change to a 4
3rd submission the rating may stay at 4
4th submission the rating may change to a 2

Should I be using the same Agency Id for each of the submission or should each submission be unique with each submission whether the data has changed?

We, in for CPIC/Spike, have the historical data to review locally so it is likely not important to track it on GSA.

Thank You,
