Compass does as well, 2.5 hours/day of every day you put in for Mil Leave. They also request you give them advanced notice of the day you want to use, but for their benefit they say so it won't mess with the schedules. I give them the drill weekends I need, bid my schedule and drop as I need to or adjust, technique only. I think PBS is what most company's use, so that is the feature they work with.
