Multi Day tasks expressed in days not hours

Multi day tasks canbe specified with length in hours but its cumbersome, you should be able to specify them in length of days. e.g. Curating a painting takes 5 days.. however I have to specify it and make the calculation of 24h * 5 = 120 hrs. So I need to specify the length of the task in 120 hrs instead of simply saying 5 days.
