In the calendar across profile groups you can view not just all posts with a date saved from all profile groups, but also all multiposts saved with a date.Multiposts.
You can switch between profile group posts and multiposts on the left side.
You can filter by profile group, and as usual, by publication status (Draft, Approved, Scheduled, Published) or by publishing platform.
Like with the internal calendar, you can move displayed posts via drag and drop and open them straight in the editor to make changes.
