Importing accounts with multiple currencies

[David Lynch]

    I have read the FAQs and archives (of this group) and issues with 
importing of accounts with multiple currencies have been raised several 
times but remain, as far as I can see, unresolved.
    I'm a new user trying to import several years' data from Quicken. 
Transaction between accounts with different currencies are being handled 
incorrectly.
    Can I configure gnucash to handle them correctly? Or, if not, is the 
best way round the problem to input manually each transaction between 
currencies?
