Checkout shipping one time shipping address form more customizable

Hi,

We noticed that the one time shipping form in the checkout shipping page for Spire is not very flexible. We had 2 clients with special requirements for this form, and we were unable to add fields.

Client A: Wanted a new field for his custom taxes

Solution: We had to take the address 3 field because there is no way to add more field.

Client B: He also wanted two more fields on that form, and we had to use address 3 + address 4.

The workaround we found work well, but we think this is not optimal, maybe adding some custom empty fields with flexible front-end validation would help in future cases.

Thank you,

Fred.
