Is it possible to add support for command blocks to change region flags? For example, can I set a command block to say "region flag joust mob-spawning allow" to make my insane mob spawners start dropping mobs all over the arena during a bonus round, and then turn it off again? I attempted to change flags using command blocks in 5.6.5 to no avail.
