I'd like to build a freeform table that returns the percentage change from the prior period in the table.

Expected results would be something like my screenshot below that shows the Week period in rows and then the Visits metric as a field. The custom metric would then show the percentage lift or fall from the prior period used (week in this case).

Bonus if I could change the period from Day, Week, or Month and have the metric know this, but having separate metrics for standard date periods is no biggie. Thanks in advance!

BTW - If you utilize ChatGPT to help, don't bother - it hallucinates almost any answer for Adobe Analytics still.
