Use the following steps to set the property values of a container before it plays. This procedure uses the Clip Editor, Property Sets Before tab for the given container.
Note that the leftward green arrow becomes active whenever an override value is entered.
Additionally, the Delete PropSet icon (on the far right below) becomes active when an override value exists for a given row, in case you wish to remove that Property Set action.
For example, set the container’s password property from an underlying target’s system property, Password.
