Can I add more hierarchy to my checklist ?

[Nguyễn Trấn Hưng]

Currently I can only create checklists as shown in Figure 1 (processes in a check list). But since there are many child processes in each process, I have to create more checklists below, which is inconvenient and unintuitive.
Can I create a checklist like figure 2: child processes in the parent process, even child processes in the child process?

You can create parent-child relationships but not in the form you wanted. 

An Australian client had commissioned me to but him such an application such that he can have the ability to break down an item and have the completion  of an item registered also in the parent checklist item when item is moved to Done list.

The implementation also include predecessor, successors and related task in addition to just parent -child relationships.

He is using it to track - tasks, issues, features, various types of document...etc

Due to its complexity and preference, not all the features can be done natively with Trello Automation so there are a few http requests.
