Extrusion line options?

[cravencr]

Sup all,

I was wondering where and if there are mutable options in the API for changing how the extrusion lines are drawn.

My use case as follows:
I have a series of KML Placemarks with extrusion set to '1'. The default white line rendered for extrusion may be confusing to the viewer because I have custom rendered lines representing the velocity vector of the placemark. What I'd like to have is maybe an opacity value or dotted/dashed option for the extrusion line.

Thoughts/Comments?

Thanks.
