If you are using multiple reports in a dataset or a metric, it can become hard to remember which report contains which data—especially if you are using multiple datasets or if some reports are using the same data source.
You can add a label to each report to help identify what data the report contains or where it comes from. To do this in the metric builder, click on the down arrow at the right of the report tab to open the report menu, and click on "Add Label." A window will pop up to enter the label. Click "save" and the text will be below the report header.
Only the first 25 characters will be visible in each report tab in the metric builder.
NOTE: When referring to reports in a Master SQL report or in Spreadsheet Functions, you will still use the report number (e.g., "report1")
