You can save the layout of an existing report to an external report file. Then you use this external file as needed; for example, to customize the report layout outside Alloy Discovery.
To save the report layout to an external report file:
On the main menu, click Reports > Reports and open a desired report category from the Categories pane.
In the Reports grid, right-click the report and choose Save As from the pop-up menu.
Browse for the destination folder where you want to save the file. By default, the file name is the same as the report name. If you want to change it, type in a new name in the File name field.
