I know the Airplayer is targeted to a Campaign->Screen
Say, I have a Campaign that has three screens. In the business location (lets assume a clothing store), one Airplayer is playing screen1 - a loop of "Boys Clothes" and another screen2- a loop of "Mens Clothes" and perhaps a third monitor is playing screen3 - a loop of "Women's Clothes".
At 5 minutes to 5pm, I want all the screens to show a notice that the store is closing in 5 minutes.
How do I do that?
Or every hour, I want to show today's sale items on all three screens or maybe just one or two?
