Hi @Devon Bilsing,
If you select the KPI in the report within TBM Studio, and you select the KPI option in the ribbon, there is a button there labeled "Shorthand." You can specify the Notation Type and have that KPI specifically rounded to the thousands, millions, billions, or trillions.
The option labeled All Notations will automatically select the best rounding, but will default to two decimal places in the example that you mentioned above.
One thing to keep in mind is that if you're modifying the KPIs in this way on an Out of the Box report, you'll need to re-apply these settings after an upgrade as this would be seen as a customization of the report. However, if it is a custom report that you've built, then you won't have to worry about re-applying these settings post-upgrade.
Hope this helps!
