In this example, a user has set up custom column comparisons so that each column is tested against the last, most recent time period column (ex., letters A/M, B/M, C/M, etc.). When part of a tracking study and a new wave will be added, the user has to go in and manually adjust the custom comparisons so that they would reflect A/N, B/N, C/N, etc. or drop the oldest wave of data to ensure that column "M" is always the most recent time period.

Requesting the ability to give users the choice to automatically update custom comparisons as the data changes (ex, new waves are added).
