Does anyone know how to create leader lines for an extent indicator that follow the shape of the data frame? For example, if your locator map (data frame) is a circle, how can you show two lines extending from the indicator circle on the map to the large one of the detail? (kind of like the Batsignal in the image below). Or similarly, doing the same thing with a square or rectangle to extend it like a pillar. This would be really nice functionality to have in ArcMap, because as it is, I've done these in the past but with simple lines (created using the Draw tool), but it's tedious and doesn't always look the cleanest. Any suggestions would be appreciated.
