add the option to record money returned
At the moment, we can record an advance given to employees, but we can't record any money they return. As they don't always return the same currency as they were given (i.e. we give the USD and they get it changed into Kenyan Shilling, but return some shilling), it would be much easier to be able to record the returned cash as a separate transaction.
The only way we can record it at the moment, is to convert it and deduct it from the original advance, but this makes it more difficult to understand later.
