Hi @Connor Irwin,
I've taken a look into this. The way that table is structured, with the months in columns, it seems that you could create drill-to reports for each month, and link those based on the columns. It sounds to me like that might be quite a bit of maintenance going forward (needing to create new drill-to reports for each month), and quite a bit of work to get things up and running with the creation of all of the tables linked to specific time periods.
Rows are definitely manageable, and can be done like you were saying you've seen in the videos. Columns are trickier and would likely require the creation of separate drill-to reports.
Thanks!
Katie
