The Overall dashboard has lot of reports in it.

Each report in the dashboard will have its own drill down report to show the details.

if the user clicks on the report, it would be ideal to open the "Drill down report" - new dashboard in a separate tab instead of overriding/redirecting the original report. it makes the user to click "Back" button to reload the original report

 

If we have the option to open the drill down report/dashboard in a separate tab

1. User can retain the original report and no need to reload again

2. User can open  multiple drill down reports and can view all the details - side by side
