How does once provide a pattern for file naming while processing ISO 20022 Credit Transfer pain001V3

Summary:

Currently the system spits out a random # as the file name with an extension of "*.xml" as the file when a payment is processed by using the seeded ISO 20022 Credit Transfer pain.001V3 template.

The requirement is to provide a pattern for a file name with variables which should be replaced at run time.

E.g.,

The Debtor Bank Code, DateTime Stamp in a specific format, underscores in relevant positions

How can achieve this?

Thank you!
