It would be very nice to have multi level grouping for timeline & gantt & pivot table layouts.
Use cases: Projects involving different tasks to be completed by different people in different addresses. It gets very complex to track each of these tasks without knowing where they are, to whom they were assigned to without multi-level grouping.
I developed a workaround by using a formula field that concatenates Location&Assignee&Task Name and sort them but it doesn’t work as the concatenated field does not fit into the allocated space.
