Fusion BIP Print Receivables Transactions with swiss QR bill / swiss QR code

Summary:

We are searching for a Oracle Fusion Cloud working process on how to create and include a swiss QR bill (payment and receipt part) into the Print Receivables Transactions process.

I saw this question coming here a couple of times in the portal, but still missing a working solution for this requirement.

I need a solution which is working with the Print Receivables Transactions process using an RTF template for creating the document.

As we are on Fusion we are limited with the possibilities of using external java libs, creating triggers with db-packages or doing complex rest-calls as you might imagine.
