Manual editing of dates in History

Hi,
I want to set precise dates for my history graph. It turns out that using the GUI isn’t practical at all when the period spans multiple months across two years or more.
Would it be possible to add the possibility to edit the start and end dates manually in the dd/mm/yyyy format ?
Thanks.
