Add tasks, as well as Phases and Milestones, when creating Schedule Templates Merged

We intend to use Aha! to create a Project Management workspace for our client services projects, which deliver the software services critical for the success of our products. When creating project plan templates using the Schedule Templates functionality, we can only add Phases and Milestones. It would save us a significant amount of administrative time if we could add tasks to our schedule templates before we use a template to create a project plan.
