Exchange rate in reports

[Artur Chruściel]

Hi All,

When I'm buying book for $5.00 my credit card is charged to 15,00PLN. 
Transaction between Books:USD account and CreditCard (PLN) account has 
its own exchange rate and it is clearly defined in the GnuCash. So in 
the Income Statement report I would like to see 15PLN spent on american 
books. Unforturtunately, all four methods of definig exchange rate can 
create only one rate for whole report. Because PLN is my main currency, 
I'm loosing very iportant infomation: my real expenses during the report 
period.

Currently I'm dealing with this issue using Books account in PLN only 
but this causes loosing of exchange rate instead.

Is it possible to have them both: exchange rate and real cost of item?

My only idea is to have CreditCard and Books accounts in PLN and create 
transaction between them using dummy USD account. But it looks like not 
needed overhead for this case... (And, of course, only for this case. I 
understand that exchange rate for i.e. USD -> USD transactions needs to 
be counted for report in PLN.)

Best Regards,
Artur
