Can Scheduled Absences be less than 1 day in duration

In the User Editor on the Scheduled Absences tab, I don't see a way to
enter anything other than full-day absences. Is it possible to
schedule 1/2-days somehow?

As the enhancement for this has not been implemented yet, Work allocations could be used as a workaround

• Let’s say I have defined my normal work allocation for Project/team X to be 50%
• Now lets say for a specific day, I normally work 8 hours but I’m going to schedule 3 hours of absence in that day.
• I add a new work allocation for that specific day set to 31%  (based upon 50% * (8-3)/8 = ~31%)
