Do you ever rollback imports?

• How often do you need to rollback Bank Statement, Cashbook or Bank Details imports?
• Why do you need to rollback?
• Do you rollback an entire statement/import definition or just for the affected accounts?
• If you need to rollback how do you do it? Adhoc script; standard script; Delete the affected Bank or Cashbook Batches per account from the UI?

Let me know in the comments or by email. We are looking at ways to make it easier to manage.
