Payment schedule modified on SO before invoice should be considered.

We have a workaround but it does not help customer.
If the user wants to change the dates of the payments then the user needs to change them after they click Invoice. There is a payment schedule option in the Overview section. Click this, click Yes to the message that appears and then they can edit the due dates in this payment schedule form. If they edit the dates here, once the invoice is posted it will keep the payment schedules date changes.

Customer business requirement:
It’s possible to change the date of the payments (before invoice) only when we invoice the sales order (by posting invoice), but in our business, we invoice the sales orders en masse, so it’s impossible to change the payment dates SO by SO at the moment of the invoice. Therefore, I insist that we need to change the payment days before invoice by payment schedule not by posting invoice.
