Payables invoice address not Showing 'Address Line 2'

Summary:

The address on the payables invoices are not showing the Address Line 2 field, only a concatenated string with Address Line 1, City, State & Zip. Is there a way to update the address to show the extra field?

Content (please ensure you mask any confidential information):

I have gone in to edit the invoice page field to see if I could edit the Address field to add address line 2, but it is not an option. The field shows "#{(bindings.InvoiceTypeLookupCode.inputValue=='PAYMENT REQUEST') ? (bindings.PartyAddress.inputValue) : (bindings.VendorSiteAddress.inputValue)}"

Looking for a way to update the PartyAddress/VendorSiteAddress to include address line 2 so that the concatenated address string shows Address Line 2 from our supplier.
