You have the ability to group multiple Blocks together to form what we call a Stage. A Stage can be created by dragging and selecting multiple Blocks in your canvas to put them together as a Stage. Once a Stage is created, it is saved and available within that Project for you and your team to reuse and organize your Pipeline workflow. This also allows you to control the usage of certain elements in your Pipeline by making sure your team members use the Stage you built instead them rebuilding that piece in a different manner. Double clicking the Stage will let you edit the instance.
