In the current timesheet, there's no straightforward way to view total time at the parent task level with all subtasks rolled up. I've tried the Time Reporting and Timesheet cards, but neither allows this breakdown to be viewed by day.

Additionally, in the timesheet view, the parent task of a subtask isn't visible without hovering over or clicking into it, which makes it difficult to get quick context.

My ideal solution would be an expandable List view — starting at the parent level and allowing me to drill down through the task hierarchy individually, with time totals rolling up at each level and remaining broken down by day.
