But you DO NOT use Import

From Help:

Adagio BankRec allows you to import transactions from your bank for Matching to the Bank Reconciliation.
It will allow you to import Bank Statements in OFX or CSV formats.
For OFX, there is no need to define an Import Template.
Simply choose OFX as the Electronic recon. file format on the Interface page of the Bank Record.
