Your accounting software doesn't support CSV templates? I had a similar issue with a different bank and in the reconcile feature you can pick the template (eg QBO, CSV, etc) and under CSV are the templates I made (along with stock templates for $BigBank). So I only made the template once with a little drag/drop page and was done. All subsequent imports are "one click" easy
NetSuite requires CSVs to be in a predefined format. No mapping options at all. [1]
(You might think "just don't use NetSuite" but most large companies are using NetSuite. Small-business accounting systems do not work well past a certain scale of transactions/purchasers/vendors/etc.)
