Enable another layer of nested subtasks to show up in filters beyond 3 layers when adding subtasks to another list.
We want to be able to plan Theme/Goal, Objectives, Key-Results, Initiatives, Tasks, etc.. using nested layers of subtasks all in one list. When finished planning I would like to add the deeper nested subtasks into other lists for other teams to work on.
For example, when I add "Initiatives" (4th nested Layer) into another list. I cannot see it's nested subtasks when "Show Subtasks as Separate Tasks" is selected.
All we need is one more layer. Others users may want more.
