Use the view reference parameter to color all callouts such as section cuts that reference other views.
For example, a plan view has 40 section cuts; 8 of them are live sections and the rest reference those live sections. It would be very useful to assign a different color to the ones referencing another view to quickly identify which are the live sections.
There is a system parameter that magically adds the Reference Label to any callout with the Reference Other Views parameter checked, allow us to access this secrete parameter, perhaps with filters, to make all reference view callouts look different.
