@Ziv_Solomon - Ah, ok now I am following, thanks for the explanation! That is not currently supported. I did find this request in the forum:
I think that covers what you’re trying to do. Please give it a vote!
In the meantime, what we do is utilize task templates as a “section template” to give us composable blocks within a template. We have a bundle with task templates, where each template represents a “section” (container) containing sub-tasks (tasks). We instantiate the project, then instantiate our desired “sections”. We then drag the subtasks out from within parent tasks to become top-level tasks and delete the “section” container.
