Is there a way to show the sheet name in calendar view of a report?

I am trying to pull together multiple project schedules into a report that I can view as a calendar- basically showing the key milestones from several projects on a single calendar. When I am in Gantt view, I can clearly see which project sheet each milestone comes from, but, when I switch to calendar view, I only see the primary column information. Is there a way to add the sheet name, or even just add a two-letter code, to the calendar view? Images attached for reference. Thanks in advance!
