Is there a way to ask if the billing information is the same as address information?
You can use the logical condition for that, just trigger a condition that will insert the value of address field 1 to the address the field of the payment field.
Please refer to this guide: How-to-Insert-Text-or-Calculation-into-a-Field-Using-Conditional-Logic
Please give it a try and let us know how it goes.
