Roll in armorstand

A lot of players already know that you can go into an Armor Stand while in spectator mode. Some players also know that you can flip your screen upside down while spectating one, this is a great feature for theme park first person roller coasters, and for map making! But there is one thing that I dislike and that is that the player's view is not affected by the roll of the Armor Stand, it's just the player's pitch and yaw that are affected. It would be really great if we could also change the player's roll, it would make everything so much more intense!
