Customizable Sections inside Daily View of Scheduled Tasks

I have a lot of daily actions to complete each day. It would be nice to have collapsible lists / sections that we can use for better organization and structure of our days.

For example - I have 12 tasks due today, so my day view looks like a long scrolling list of tasks. It would be nice if I could have custom sections where I can organize the tasks and toggle the list open/closed as needed. Screenshot of idea attached
