Hi,
I have a module below, a list (transaction date) on the rows and time period on the columns. Is there a way to do dynamic aggregation vertically based the list transaction date? For example, I want to have this cell (time period: Apr 18, list period: Aug 19) to show sum of transaction period Jan 19 - Jul 19 for time period Apr 18.
I know MOVINGSUM() works horizontally for TIME, is there a way to make it works for the list?

Thanks
Jayden
