If you'd like to categorize your KPIs, try the Clustering Feature.

In the KPIs section, head to the top right and click "Edit". You can then scroll to the bottom of your Revenue or Costs tab were you will see "+ Add Category".

Simply add the categories you'd like to use and then click and drag them in the order you'd like to have them. You can click and drag line items into the categories that they apply to.
