All-day 'Appointments'

I need to show events / absences in the calendar that are multi-day. The 'Appointment' field is, I think, the one that permits different start and finish dates. But, it requires to enter a time for each of the start and finish dates. There is no option to select 'all day'.

 If someone has a 4-day 'appointment' in a single record, there  is no satisfactory way to have this shown in the calendar in the same way as a single 'Date' in a record appears in the calendar. Because I am forced to enter start and finish times, the result is that the Week view gets completely blocked out across all the time slots in every day by one single multi-day appointment.
In the example in the screenshot below, I would like to have 'Janey A away' 6-9 June not showing as that orange block, but displayed as 4 separate tiles in the style of other 'all day' happenings.  Can this be accomplished?

 The current alternative  is to enter Janey's away as 4 separate date records, rather than one single appointment, but why do we have to do that? If someone has a 3-week holiday, it should be unnecessary to create 21 date records instead of 1 appointment record.
