Using "EX" or "999" or some other piece of text has been working great for me for years. This works just like a radio button...I would have to select all the doors I wouldn't want to see on the schedule...So whether I select them and then navigate to a radio button or type in 999 in the ID window seems like it would work just as efficiently either way.
