I would like to compare two different periods that do not share the same timeframe. For example, last calendar year compared to this year through August 6, for example.  One column would have 2022's 12 months' activity, the other column would have 7 months' plus 6 days' activity.

The fact that I apparently cannot customize a report this way is a terrible indictment of QBDT's manifest limitations.  How this simple customization isn't built into QBDT is astonishing.
