Select a template to add to the currently selected page, and click the Add button. The new template will be added in the center of the currently selected page, which you can now position and rotate as desired.

Note that you are also able to change the printable areas of disc templates via the Change Disc Printable Areas dialog (See: Label Layout Editor panels), which is accessed by clicking the Change disc printable areas button while a template is selected in the editor.
