Address form field needs Apt./Unit line

[KT Walrus]

The current Address field type in IPS4 doesn't lend itself for entering an Apt./Unit/Suite # to complete a full deliverable address.

Since the Address field uses Google Maps to autocomplete on the Street Address line and Google doesn't add apt/unit #'s to the autocomplete address, users don't always add that info to the addresses they provide. I want to use some of these addresses for delivery on my site.

Please add an extra input field (under the Street Address lines) where the input field has a placeholder that encourages entering the apt/unit #.

See Amazon's Address input form for an example:
