Address Book.app - Apartment number field? There's no 2nd Address Line?

Hi,

I have been using Apple's built-in Address Book to keep track of contacts. I am disappointed that the application seems to lack a second address line for apts/suites. This leads to me having to place an apartment number on the first line which isn't always convenient especially when using Address Book to fill-in web fields.

Is there something I'm missing? I checked the fields that were available to add and a second address line was strangely not available.

Help please!

Thanks,

Patrick
