Revit :: View Templates And Detail Lines

Detail lines have global view settings - you cannot change appearance with a View Template. The Detail Items V/G category doesnt seem to include detail lines.
 
It is often necessary to use detail lines to avoid the chore of mading up a family to represent simple objects in plan or section - eg complex fixed furnishings like counters and shelves. Then when it comes to doing a schematic electrical layout where I want everything greyed out except the electrical content, I can use V/G overrides on all family content but not the linework. I have to pick all this invidually and  then Override Graphics in View.
 
As with V/G template overrides, I dont want these overrides to permeate globally hence not changing line styles.
