Some Google Sheets data might be metrics where a decrease over time is positive, such as cost. Would like to be able to set whether an increase or a decrease is a positive change.

Costs going down is a good thing and would ideally be green, and costs going up would be red.

it shows the decrease as red, when really it should be green as going down is a good thing.

Ability to change the "good" or "bad" red/green when comparing
