You can copy Query, OLAPQuery, Chart, Pivot and Dashboard sections if the Duplicatable feature is selected.
To make a section duplicatable, select the section label in the Section pane and select Edit, then Duplicatable.
To duplicate a section, select the section label in the Section pane and select Edit, then Duplicate Section.
Interactive Reporting duplicates the section and adds a new section label to the Section pane. The new section label is based on the original section label, but a sequence number is appended to the label. For example, if you duplicate a section named SalesChart three times, the Section pane would show: SalesChart, SalesChart2, SalesChart3, and SalesChart4.
