Show layouts scheduled as part of display group also in the individual display

For example, I have a group of displays called Elevators. I scheduled a layout for the display group "Elevators". Later, when I am viewing only Floor 3 elevator and not the display group "Elevators", nothing shows on the calendar if it was scheduled for the whole group. This is confusing when I need to set up custom layouts for a single elevator, I can't tell that there is something already scheduled at that time. With systems that have over 100 displays, it is difficult to know which displays belong to which display groups. Potentially a display could even belong to 2 display groups.

I think the functionality would be similar to other calendar program functionality when you create repeating events. An icon can show next to items that were scheduled as a group (similar to how recurring events on a calendar sometimes have a special icon next to them to show they are recurring). If you go to delete one, it asks do you want to delete just this occurrence or all occurences. The same way this could say do you want to delete the schedule for just this display or all displays in the group (could even list the other displays in the group).

The coding may be complicated, but I think the usability would be more intuitive for a user familiar with calendaring applications.
