Is it possible to send two attachments PDF & XML Print Receivables Transaction?

Summary: We have created an additional XML template for one of our clients and are currently using a UNION in the Bursting query to attach two files (PDF and XML) to the email sent to customers. However, the system is sending two separate emails: one with the PDF attachment and the other with the XML attachment.

Is there a way to combine both attachments into a single email instead of sending them separately?

Thank you for your assistance.
