States for moving platforms

[KodyBits]

I wish all three types of moving platforms would have states like those big gates, which can be either closed or open. Obviously it is possible to save a state (open/close) per object looking at the doors (and Planet Coaster 1). So why isn't it possible yet to to the same for those moving platforms? This would give much more control over animations and appearing / hiding animatronics on dark rides or coasters.
