When trying to receipt goods on the mobile device from a return order, the system asks me for a batch number

On the return order, i used the 'find sale order' functionality to add the return line, so i would have assumed that the system picks up the batch from the original sale order
(in my case the sale line only had one batch).
But this was not the case. the warehouse operative will not know the batch number.
So does this mean we have to manually specify the batch on the return order line for batch-controlled item?
Is there a way to have the batch number from the original sale line default in? (either on the return line or on the WHS app)
