How to do a market order on cryptsy

[neuromancer56]

When I buy or sell coins on cryptsy, it defaults to the current best price.   However, I usually only buy/sell a portion of my coins at that price.   Then I have to wait for someone else to come along and meet my original order price.  I had heard that Cryptsy was coming out with a market order feature.  Is this what I am using, or is there a feature that allows your price to be automatically adjusted until all your coins are bought/sold (near) immediately?
