Reason Code when we update the order quantity

Summary:

We have orders where the header is in Processing status and lines in Awaiting shipping. When we create a revision and update the order quantity, can we enter a reason code? We are unable to see any field to enter the reason code.

This is required for audit/reporting purpuse to understand why the order was amended.
