Never tried it myself, so don't blame me if you freeze your fingers off.
Found this on the net...You could probably use your powertank and a blowgun tip. "Just open the hose into a burlap bag and then pack the dry ice snow into a container."
I know that at my job, they use a small wooden box (8"x8"x10") with hinges on 3 edges (so that it opens easily after the block is formed). So I believe the burlap bag can also work, you probably wont be able to take the block out of the bag, until the ice has evaporated. You don't want to deal with the liquid, just get the gas to expand quickly within a confined space. Although it is not very efficient, about 46% of the gas will freeze into dry ice snow, the rest of the C02 gas is released into the atmosphere.
Just make sure you're using thick gloves (like heavy welder's leather gloves) when handling dry ice.
