The filter function is a powerful feature, because it allows you to quickly hide certain parts of your project (tracking points) from the report. This is useful for optimizing a project along the way. You could also use this for vieweing the incremental reach for a specific tracking point in your project. There are many possibilities!
How to use it
You'll find the filter function in the top right corner of your reports. When you click it, you can easily choose what tracking points you'd like to include in the report.
