Yes, we have one (two?) at our shop. The center post is hinged at the header and swings up with the help of a winch. The vertical tracks are longer than normal so that the top of the vertical is even with or just above the header. We have done several of these for small hangers, and have manufactured several ourselves for larger jobs where the door manufacturers don't want to bother with it. Last year we did two hangers, the larger of the two had three doors with two swing up posts for a total opening width of 90 feet. The two outer doors were 20' high and the center door was 24' high. Pretty interesting project.
Wayne-Dalton will make you a pair of doors with a swing-up post, ready to install. If you are feeling industrious and want to make it yourself, go for it and good luck.
