Is there a way to open incognito windows with separate cookies in Chrome?

If you open multiple incognito windows, they share the same set of cookies. I’d like to be able to open windows and have separate sets of cookies (e.g. for testing multiuser applications that require cookies). Right now I do this by using separate Google profiles and using multiple versions of Chrome, but that is a pain – looking for the idiomatic way to do it.
