Project filter/grouping in Scheduled

In Someday, actions and projects are grouped.

In Scheduled the default grouping is by period, with actions and projects mixed together.

It would be handy to be able to see just the projects or have the option to group action/projects.

The reason is the very different nature of a scheduled action vs a scheduled project.

The Scheduled list is mostly useful to review upcoming activities. How is a project different from an action in this scenario?
