Removing transactions from a settlement batch

hi there
Has anyone come across a situation where a funds capture settlement batch had to manipulated and transactions removed before the EFT file could be sent to the bank.
We have a situation where a settlement batch will be checked by business user before the EFT file can be approved to be transmitted to the Bank for the Funds Capture.
If the batch contains some transactions that for business reasons should not be there then,

• how do we "reverse" it cleanly out of the settlement batch and also from AR and perhaps re-process it later after checks have been performed.
