The Default Batch payment report appears to sort itself based on the Payment Journal ID Number, How do I change this so it sorts by Customer / Vendor A-Z?

I assume the 3rd line    <t t-foreach="docs" t-as="o"> needs a 'sorted' command but I have no idea on the python / Odoo code.

Any help & guidance is most appreciated!
