In Amazon Quicksight, you have the ability to create a "Period over Period" insight. This would, for example, show "Sales increase 10% from January 2020 to February 2020.
However, it seems that the "current" period is not configurable and always takes on the period a user would find themselves in. This means that the statistic is a little misleading since on January 2nd, it might say "Sales decreased 89% from December 2019 to January 2020". While true, it's not apples to apples since January isn't finished yet.
Is there a way to have it compare the last two completed periods? For example, if January 2nd, it would compare November vs December?
