Am I Able To Change The Dates (Post-Setup) To Import Historical Data?

Yes. Bank Feeds can retrieve up to 12 months of historical transaction data from the date of connection, depending on the reconciliation status of your cashbook month in Agrimaster Cashbook

When setting up Bank Feeds, Agrimaster will determine how far back transactions can be brought into your cashbook based on your current reconciliation position.

This means you can access historical bank transactions without needing to manually enter them, making it easier to bring your cashbook up to date.
