I should be possible to create an invoice proposal where we settle the vendor invoice in the currency of how the invoice was posted and then have to possibility to select to have the offset account posted in the currency of the master data setup on the bank account.

This allowing for companies who mainly have bank accounts in local currency to be able to post the local currency to the bank to ensure the possibility to match amounts 1 to 1 during bank reconciliations and also settle the amounts on the vendor account in the currency and amount of the invoice, just having to adjust the exchange rate according to the bank's spot rate.

This will most likely require that one transaction in the journal will have to be split into 2 lines, no offset on the first line and the offset on the second line.
