Help gnucash recognize recurring transactions: Is it possible?

Looked further into how GnuCash might be trained to recognize and correctly categorize recurring transactions imported from OFX bank account files, and found no documentation, although it does have some sort of Bayes scoring capability to do this.

Not looking good. All documentation and discussion points to directly editing the huge .gnucash XML file that holds all the transactions and everything:
