Multi-currency expense accounts

[T Yeoh]

Hi
The expense accounts seem to require a currency during set up or it defaults to home currency $
When I use the expense account (e.g. "Taxi") under a foreign currency cash account and enter say EUR23, the entry registered in the "Taxi" account is $23 without FX conversion which results in an incorrect total
Short of having to duplicate the expense account in the foreign currency, is there any other way to handle this such that the expense account entries are correct? Having a set of "Taxi" accounts in different currencies may be cumbersome as the number of currencies involved increases
