Prior ratings in the Nine Box Dashboard are being overwritten by current ratings

Summary:

Prior ratings in the Nine Box Dashboard are being overwritten by current ratings after the Talent Review Meeting; can we retain the original prior ratings separately?

Content (please ensure you mask any confidential information):

We have configured the "Prior Rating Dates" to fetch the previous Talent Review Meeting ratings of the review population in the Nine Box Dashboard. However, we’ve observed that once employees are rated during the current Talent Review Meeting, both the "View Prior Rating" and "View Current Rating" are displaying the newly assigned ratings.

Ideally, the "View Prior Rating" should continue to reflect the ratings from the previous Talent Review Meeting, without being overwritten by the current cycle’s ratings.
