How exclude power Pylon?

I am buidling a airstrip near Codroipo Italy. I have a power Plyon on the centre of runway. How eclude it? I cann’t make this:

leaving an hole.

You cannot. The SDK team has not yet developed this functionality. It is on their list and they are working on it.

They announced this feature in the sept 30th development update:

You will soon be able to exclude roads, power poles, and street lights using polygons.

so maby we get it as an SDK Update together with Su6?
