We are using the Scrum method to organize our work. To create a product backlog task or a sprint task we created specific forms that have some predefined values. To create a new sprint task we currently make use of this form and after creating the task we manually add the parent (product backlog) task as related object and manually add the projects of the parent task to the sprint task. For us it would be much simpler if we could start from the product backlog task, then add a sprint task by clicking on Create Subtask and then select the specific form we want to use.
Add the possibility to choose a specific form when you click on Create Subtask of a task.
