Based on the reply from their support, I don't think we'll support this. Closing.

We format the Address on behalf of the merchant when the transaction is sent through Hosted Checkout's payment page.

If the API is used, the address needs to be formatted per the Bank processor's requirement.

If contents were separated by " | " when TSYS is used, I suspect that would cause an issue on TSYS's side as the address value submitted would not be in the expected format.

I would recommend storing the payment processor used by the merchant and adding a condition based on it in order to make sure the right address format is used.
