If I incur a foreign currency charge, for example for EUR 100.00, my bank will show a transaction of the equivalent USD, say USD 110.00. But at the end of the period, they then add another transaction for say USD 1.10 as a FX Fee. If I first record the original EUR 100 transaction with an exchange rate to match USD 111.10, no problem. But when I later match the card transaction of USD 110.00, it turns it back to $110.00, but still shows USD 111.10 in the transactions currency conversion.
It should allow the USD 111.10 if that's what the currency conversion says, or else there should be an adjustment value you can apply.
And I should be able to do this with adding the two amounts together, then back-computing the exchange-rate.
Thanks!
