I would think that it would be unusual to have a 3 panel door with only one end panel sliding.
Usually 2 panels would slide.
Not to say this couldn't happen though.
In the AUS library the standard "Sliding Door 22' has a 3 slider option.
Unfortunately there is no option to have only one panel sliding.
I don't have the INT or USA library loaded so I can't say if this option is available in those libraries.
