Listing is free, why even if what you wanted was possible, would you want to pay a fee, when all you need do is list at the price you want to sell for. Can't sell for less.
At the best of times Reserves are a waste of Money, the fee is 4% of the Reserve payable sold or unsold. If you want to do anyting add "Best Offer", it is free and you don't have to accept any offers unless they are acceptable.
