I've saved some stuff into Authorize.net through it's CIM service and I'd like to update a few fields in Authorize.net. If I pass in the credit card number as x's, like this xxxxxxxxxxx1234 as shown [here](http://community.developer.authorize.net/t5/Integration-and-Testing/Can-update-ARB-card-expiration-without-card-number-in-authorize/td-p/16234).

The problem is that there's validation done in the CreditCard of ActiveMerchant, and it doesn't allow me to use that information. How would I go about update the information in Authorize.net?
