You either wait to upgrade to a version of the switcher that supports RossTalk "Type In" commands - and then use the RossTalk "LayerOff" command to trigger the out animation of your XPression graphics...
Or...
Create your XPression graphics to have a pause, the out transition, and a Take Offline event. The graphic will go online, Pause, and then the swticher will Resume the graphic (a second play command), and then the graphics transitions off.
