gur non play zone hole 7

A ball cannot be lost in gur or non playable zone, the rule is nearest point of relief if the ball is found but if not then drop behind where it last crossed the area.   If a hook shot puts the ball in the left side of the area a drop into what is most certainly a very poor lie ensues.   The question is this if I put a ball in the left side can I just declare it lost and drop in a more favourable place.     I personaly think that a drop zone should be marked  where any ball going in should be played from.   Any thoughts except don't hook into the left!
