Hierarchical tasks with queryable subtasks (checkboxes or child tasks)

I’m using Capacities’ new Task object extensively and I’d like to model subtasks in a way that is both:

• Hierarchical – subtasks are tasks that belong under another task (not just under a project or other object type), and
• Queryable – I can get a global overview of all subtasks across my space.

Right now there is no explicit subtask concept for Tasks. I can add checkboxes inside a Task and treat them as subtasks, but I cannot query all checkbox items across all Tasks/objects.

So I can’t get a global “all subtasks” view.

I also cannot add custom properties to the Task object , so I can’t model a clean parent/child relationship between Tasks (e.g. Parent task, Subtasks properties).

Because of this, my task list “explodes” if I try to model every subtask as a separate Task object, and I still don’t get a proper hierarchical view. A flat task list with dozens of items is practically unusable.

What I’d love to have.

I see two possible directions (either would help a lot):

1. First‑class hierarchical Tasks

• Allow Tasks to have other Tasks as subtasks (parent/child relationship).
• Make this relationship visible in the UI (expand/collapse subtasks under a parent).
• Make it queryable (e.g. filter for all subtasks of a given parent, or all open subtasks).

2. Global querying of checkbox subtasks. If subtasks are meant to be checkboxes inside Tasks, provide:

• A way to query all checkbox items across my space.
• Filters like: “only unchecked”, “only those inside Tasks”, “only those inside Tasks with status X”, etc.

This would let me keep subtasks lightweight (checkboxes) but still have a global overview.

Either approach would solve the core problem: I want to use subtasks without losing the ability to see and manage them across my whole space.
