I believe the "drum" rolls up counterclockwise (looking from the front), so I wouldn't think that was possible.
My first question would be whether you have enough "stuff" on the bottom of your awning to justify trying that?
Also, you would most certainly not want to leave it that way because then it would collect water while it was rolled up.
