Hi there,
I live in Brazil and pay for many services in US Dollars using my Credit Card. For example:
2016-07-17 * "Apple" "iCloud 50GB"
Expenses:Subscriptions 0.99 USD
Liabilities:CreditCard
In the end of every month I'll pay all my credit card expenses in Reais:
2016-07-18 * "Card payment"
Liabilities:CreditCard 91.84 USD @ 3.3 BRL
Assets:Bank:Checking
Since the credit card company only determines the conversion rate between USD and BRL at the payment day, is there any way for Beancount to automatically convert my expenses using this conversion rate and show me how much the transactions costed in BRL on my reports?
