Easy - and no un-weighing, flexion or extension are needed!
From a perfectly balanced position during a traverse the skier can simply implement Independent Leg Steering
(ILS) to initiate the beginning of a skidded turn.
If ILS is done progressively the skier will start their turn gradually (no pivot) with no need to extend, un-weight, flex, counter-steer, nor anything else to drive a direction change.
To me, your recommendation to use an un-weighing move suggests the skier needs to use their upper body
to initiate the turn via upper body rotation as out skis don't need to be un-weighted at all to begin an Open Parallel (skidded) turn.
Whether that specific CSIA Task permits ILS to drive the turn or not I've no idea but I suspect they wouldn't want to see an upward & downhill lurch of the upper-body to start the turn.
