Pipelines in Timeline view

Timeline looks like a super powerful tool for planning and staying on track. I love it so far. I set up my Product Development pipeline according to the Product launches section of the guide, and I’m hoping I can use Timeline with this set up. Is there an easy way to use the Timeline view with this kind of task structure, or do I need to reorganize the project?
Here’s a rough sketch of the way my product development pipeline is set up:
Project: Product Development

  • Task (current product) [custom fields with status, product line, launch date, etc]
    - sub-tasks (action steps toward product completion)
    - sub-tasks (action steps toward product completion)
  • Task (next product) [custom fields with status, product line, etc]
  • Task (next product) [custom fields with status, product line, etc]

I think it would work if you could see subtasks in the timeline view. I’ve read that Asana has gone back and forth about the idea of sub-tasks showing up on calendars, but what about Timeline? It would make the feature much more powerful for anyone who has ongoing projects and needs the actions to live in the sub-tasks level.
