How to register a transfer from one bank account in NOK to another in EUR, when the bank uses a different currency exchange rate than in Odoo.  Company currency is NOK.

The bank will always use a currency exchange rate less favourable for us, than the official rate used in Odoo. (Odoo automatic update from ECB).  

I can register correctly with a direct Journal entry.  Then I can see the what Odoo calculate as exchange rate and post the difference directly. The problem is that this entry will not come up in Bank statement reconciliation. Then I cannot close my bank statements

If I use the function for Payment -> Internal transfer, I cannot modify the value in the receiving account.  I am stuck with this issue.
