If we create a transaction (credit notes, invoices, payments) against Customer account A, we want to be able to move it to Customer B, without the manual process of redoing invoices and credit notes.

For example, if the payment got posted to Customer B instead of Customer A, we would have to credit the invoice within Customer A and reinvoice within Customer B, so that it matches the posting.

We just want to be able to move the transactions a bit easier, rather than the manual process.
