Hi
You could create a scene that has text boxes bound to the Datalinq values you want to display, then create a Virtual Output and put that scene to line on that output.
Alternatively, have text boxes with the alpha turned off on the render tab, and you can then have that scene online all the time, and those text boxes won't get keyed on - assuming your doing lower thirds!
