Dashboard designer
All fields to be used by the new dashboard template should have been selected (see point 4 Create a new dashboard).
On the left, in the Data source section, all selected fields are listed.
Insert the wanted item from the ribbon and drag the fields to the Data items section.
The small arrow on the buttons in the Data items section can be used to change the properties.
Click Save to save the dashboard. The saved dashboard can then be used when exporting by using an existing dashboard.
