Set of processes as advised to achieve the above is convoluted. Need to have a cleaner way to indicates dependencies between checklist items (whether within the same card or in a different card). Is this feature on the roadmap?

Until then...I will explain that Trello is inherently a flat system but you can very effectively create hierarchy with it.

Another amazing tip is to use this linking to be able move dates of linked items, giving you that dependency management within Trello.
