Export Data both contacts and invoices

Export Data both contacts and invoices

Hi
We need to work with SEPA European rules of Payment. I know this is impossible by now. I hope this will be possible in a future time.

Then, we need export data to excel and then send by bankś software, but we have a problem:
We need contacts data (because we have 2 customer fields we need put in the excel, IBAN, SWIFT code) and logically, all the invoices data .
Now we can find anyway to export both contacts and invoices in a only one excel sheet.
Itś possible?
