In admin on the customers page, I would like there to be a catagory that shows the birthdate of each customer. Right now it only shows: ID# , Last name , First name , Company , account created , last login , pricing group , authorized.. And I am having to click on each and every customer one at a time to see the birthdate, (lol, very annoying when you have hundreds of customers).

Is there a code or something I can add for the birthdate to show on the admin / customers page? If so, where can I get the code and where do I place it.
