E1: 9.2 P0411:Voucher match: can tax zone be modified?

E1: 9.2

P0411 User created a batch and then before posting it realised that the tax zone was incorrect.

Is it possible to modify this zone without finalising/posting the batch and then reversing it?

ref: Accounts payable, (supplier invoice), Voucher match, (batch 3282071), P0411 W0411K, (repartition GL) field TXA1.

As ever any help much appreciated.

Thanks in advance,

Mike
