Anyone? ^_^

Title pretty much says it all, I have a stack of 17 scavenged items from slicing that I want to sell, but I do not want to sell it as one stack - it discourages people that might only need 2 or 4 for a single item creation. Is there any way to seperate the stacks either on the AH or in your inventory? I tried looking through keybinds, options, and interface. Any help is appreciated! Thanks =D
