I have an csv file with transactions in a currency different from my default currency.
I want to generate transaction like these
Income:CUR1:FOO -6886 CUR1 @81.66 INR
My beangulp script currently generates
Income:CUR1:FOO -6886 CUR1
I have a script which fetches the exchange rate on that date. say `get_rate(date)`
How do I use this information to convert the generated Transaction to the desired one?
