Allied Conversion

There are times when there's a mine you desperately need in close proximity to an ally player's base. There's no way of converting the mine without converting some of that player's base along with it if your hero has a large command radius. That may as well be a punch in the face for your ally . I'd like an option for converting only neutral/enemy structures or for conversion to change so you can convert only neutral/enemy structures within the command radius.
