Custom schedule view for each individual list/Gantt request

I treat each list as a distinct project with its own specific tasks. However, while the tasks are individualized per list, the Calendar view in the Schedule tab displays all events and tasks collectively. It would be useful to have an option to filter the Calendar view so that it shows only the tasks for a specific list. Additionally, in the Gantt view, it would be great to have an option for preplanning the project using colorful lines that represent the main sections, rather than tying them to specific tasks.
