I work as a production manager for a small film company. When creating templates for our various types of videos (short, long, event, etc.) I want to assign tasks to general roles of the project (production manager, editor, camera 1, Audio Mixer). Then when I use the template for a project, I can assign a person to each role and those tasks will be assigned to them. If I use the template for a different project with a different crew, I can simply assign different people those roles and bam, smooth sailing.
Because the new Overview tab has roles, maybe this is coming next!
