Update Parse Address so it can parse a full address in a single field

[Bonfire98A]

Currently, the Parse Address tool cannot parse a field where the entire address, including so-called "last line" information (city/state/zip), is in all in the same field - it can only parse a street address contained in one field and last line information contained in a second field.  Can this tool be enhanced so that it can parse a full address in a single field?
