We do our own order delivery and about 70% of orders are to apartment buildings. A problem we often encounter is getting access to the building. A buzzer code is often required. Sometimes the receipient is listed in the directory and we can look them up. Often they are not. I am wondering if there is a way to add an optional field for shipping which says something like "Buzzer Code (If applicable)"?
I know there is a field for shipping line 2. I don't want to overwrite that because we need that for the order number but ideally right below it.
