You may temporarily change the order in which the influencing events appear in the Data Input Tree by clicking the Reorder button. A dialog will offer the events available for reordering.
Select the event you wish to appear as the left-most node in the data tree and click on OK. Repeat for the remaining nodes. When you have selected all events, the dialog will disappear, and you can see the new Data Input Tree reflecting the changed order of influencing events.
