TN Transactions

Is there a way to update a TN Transaction? Let me explain:

A TN transaction was received and processed. Now, I want to change data in the transaction without resubmitting the transaction. I want it to exist as a single transaction in TN. Is there a way to do this?

You cannot edit the data once the transaction is persisted.If you still want to change data and resubmit you will see the duplicates.This is the standard behaviour.
