How can we allow the changes of amount to apply in creation automatic receipts step

Hi all,

In R12, At the end of the creation step of AUTOMATIC receipts in AR, we can tick or untick the selected transactions but no possibility to modify the amount applied.

what is the good way to do this ?

maybe using profile option or setup ?

If we create receipt manually, we can change, modify amount applied of the transaction

at this other hand, automatic receipt, we can not modify amount applied in creation step (which is the selected open transaction step )??

Thanks you
