I would like to see an option in the shipping rules section where I can restrict shipping carriers depending on what is in the customer order address 1 field or even a toggle.
Example: I am trying to restrict PO Box addresses only for USPS shipping carrier since all other carriers to do deliver to PO Box addresses. I can set up a rule for a carrier that does not allow PO Box addresses where the Customer Order Address 1 field does not equal PO Box but there is no wildcard character to add to take in consideration the PO Box number so the rule does not work. There is no 'contains' option in the Select Based On dropdown.
