My workspace is organised by a single list per client, each list has multiple views, one for each service and each of those views has a filter to show a specific task type. (meaning with no filter, all the tasks in that list are shown). Within each of these top level tasks (with the task type), there are just normal tasks with a task type of task. This is good per list but when i want a dashboard to view all tasks as separate, I cannot tell if a task with a task type of task is inside a specific top level task with a task type of something else. It would be useful to be able to filter tasks in a dashboard based on what the upper most parent task type is. E.g., I have a task with a type of Retainer, that has a subtask with a task type of task and that has a subtask called 'Do Something'. When I view these tasks as separate, I want to filter by 'upper most task type IS retainer', and it would only show the subtask and sub-subtask.
