Two solutions:
1. Without a separate panel: Click on the panel title > Hover over 'Inspect' > Select 'Data' and click on 'Stats' where you will find the total number of rows.
2. In a separate panel: Reuse a panel query by selecting 'Dashboard' as the data source and selecting the panel query that you want to reuse, so that the query field is unified, but it is reused in another panel.
