 ## Report time range
 
-Reports use the saved time range of the dashboard. Changing the time range of the report is done by saving a modified time range to the dashboard.
+> Setting custom report time range is available in Grafana Enterprise v7.2+.
+
+By default, reports use the saved time range of the dashboard. Changing the time range of the report can be done by:
+- Saving a modified time range to the dashboard. 
+- Setting a time range via **Time range** field in the report form. If specified, then this custom time range overrides the one from the report's dashboard.
 
 The page header of the report displays the time range for the dashboard's data queries. Dashboards set to use the browser's time zone will use the time zone on the Grafana server.
 
 If the time zone is set differently between your Grafana server and its remote image renderer, then the time ranges in the report might be different between the page header and the time axes in the panels. We advise always setting the time zone to UTC for dashboards when using a remote renderer to avoid this. 
 
+## Reports settings
