Yes. Initially, as you add revenue when you complete Steps in PIPELINE, your Revenue will naturally accumulate. If you ever need to report an update to your total overall revenue, you can manually override the total by clicking on the Controls button and entering a new Revenue amount there.
*NOTE: Once you manually override your total revenue, it will no longer be updated automatically, and must be updated manually anytime you want to update it. You can continue to report Revenue as you complete Steps, which will still show normally in your progress reports.
