While viewing reports in Analytics, you apply filters to analyze data for the context that matters to you. And if you're someone who views data regularly, you'd find it troublesome to apply the same filters every time you want to set context for reports.
To address this, we built Custom Reports to help you get to your desired context faster. You can now create pre-filtered reports on top of your default metrics and give these reports unique names.
You can create a custom report after applying at least one filter on a default report or you can even create one from scratch.
