Is it possible to control the direction during auto-rotation?
It's entirely possible.

Attitude control works the same way during autorotation as it does during normal powered flight. It's a good thing, too... during an autorotation you want to target your descent toward a suitable landing spot :-)

To (say) roll right, moving the cyclic causes the swashplate to move in such a way that the rotor blade's pitch (angle of attack) is greater during the left-side portion of the blade's travel, and lower during the right-side portion. This produces more lift on the left side, which causes a right-rolling moment on the helicopter.

The fact that the collective is all the way down and that the rotor's RPM is being maintained by airflow through the rotor does not change the way the cyclic produces attitude changes.

The anti-torque pedals still work too, although during an autorotation the pilot will promptly apply full right pedal, since lowering the collective will essentially eliminate torque from the rotor. Pedals can still be used for yaw though, as the tail rotor is still spinning (it is linked to the main rotor).

The "180° turning autorotation" is a common maneuver taught in basic training, where the pilot must set up the autorotative descent and then complete a 180° turn toward a landing spot.

For more information about autorotations in general, I recommend the FAA's (free online) Helicopter Flying Handbook. See page 2-24 for a general description, and page 11-2 for procedures/technique.

There are also lots of autorotation demonstration videos on YouTube that show maneuvering to a landing spot / 180° turns during the auto.
