Show Narration For FX gains and losses in GL Transactions

The FX revaluation gains and losses are correctly captured by Manager but no Narration is provided for those entries.

I suggest a description field is made available when entering New Exchange Rates to provide Narration/Description for those revaluation entries. This field would also allow users to enter extra information such as the source of the exchange rate (OANDA etc).

Edit:
And the narration ‘Foreign Exchange Gains/Losses’ be used as description in GL transactions report
