Currently the Fields for Name 2 are missing on the Ship-to Address and the Order Address Card.

I suggest that those fields should be added to those pages.

They can be invisible by default (visbible=false) and set with Importance=Additional.

Similiar to the Name 2 field on the Customer Card.

With this little change a BC User can simple show this field if it's required and they don't need a custom development for this.
