Foreign exchange

Can I create foreign exchange gain/(loss) account manually in Manager?
and I want the figure in foreign exchange (created manually) is combine together with foreign exchange (created automatically) and shown in profit and loss as 1 account only.

Yes you can manually create a foreign exchange gain/(loss) account but you can’t combine it with the automatically created control account into a single account, unless you create a P&L group to get a sub-total of the two.
