How to Add a "Birthday" Field to Customer Information

IN RMS Store Operations Manager, when I look at any of our customers in our Customer Database, under "Customer Properties" there is a tab for "Additional Options."  I am assuming this will allow us to add extra data points about out customers over and above Name, Address, E-Mail, Phone, Account Number, etc.

We wish to begin collecting Birth Month in order to start e-mailing out Birthday Coupons.  So I have two question.

1.) How do I add a field for "Birth Month"?

2.) Is there a way to do it such that at the POS, the field is simply a pull-down menu of the twelve months?

Thanks in advance for any help,
