Currently, when scheduling a multi-day event, the event block is in the "All-Day" event section of the calendar at the top whether All Day is toggled on or not.
We would like the ability to cover the day with the event block to make it more noticeable.
For what it's worth, our firm achieves this by doing a recurring event so 8am-5pm or whatever time block is needed gets repeated for each day of trial or other multi day events.
We especially like this feature for lengthy trials so that no one mistakenly schedules the attorneys for something because they didn't notice the "reminder" at the top of the calendar.
