That's a great question! I can understand how important it is to keep track of the lists your contacts are on. However I apologize having the ability to customize the columns on the contacts page to include your lists is not a feature that is currently available. Though we are in the process of redesigning our contacts experience and always open to ways we can better our user's experience. Having this ability is a great feature request we have tracked in your account.
