There were mechanisms like that in earlier games and the Alpha/Beta builds of World of Assassination, if I’m not mistaken. You could hide a weapon in a crate and a non-player character would then carry the crate into another area where you could then retrieve the items. I don’t think it would be too hard to expand that basic mechanism to other means like cranes, delivery trucks, etc. Maybe in whatever the next Hitman game is they’ll implement something like that.
