credit card expiration notification in aMember 4?

I don't see this as an option under the E-Mail tab in aMember 4. Authorize.net is the payment plugin being used. Am I missing the option somewhere? If not, how will the customer know to update their credit card information?

Apparently, it never made it from v3... I've asked about this as well. Hopefully they implement it sooner, rather than later.
