My company uses pre-made templates with set schedules that populate when creating a new project from a template. However, these schedules assume that the project was started on time. For rush projects, I need to edit the dates accordingly. When I try to edit start date, end date, or task dates, the automated date overrides my input. Or, the option is not available and simply reads "This field is automatically calculated by the system". I want to override this calculation and input my own dates. How?
