Make date and time inputs editable

Hello! The integration of Koinly with various networks is fantastic, however, there are instances where manual input of transactions is necessary, such as with liquidity in/out. The dropdown option for setting the date and time is convenient for a single transaction, but it becomes frustrating when multiple transactions need to be entered. An improvement would be to have editable text boxes for the date and time, as this would simplify the process significantly.
