Welcome to the forum @Matt_Weiss1 !
I fully agree, and was about to create this exact topic.
Not only is it very time consuming, the lack of this functionality also makes it very unclear which tasks in a project template have subtasks to start with.
Not to mention the frustration it gives when you’ve converted a project into a template, realised you forgot to remove yourself from tasks and subtasks as a collaborator, and are mitigating the flood of notifications you’re getting because of this.
I took the liberty of modifying the title for clarity. If you have other requests, it’s probably better create separate feedback threads for this.
I feel this is an example of why I’m advocating for: Make live projects, project templates, and my tasks variations of the same class
