Create multiple selectable handles

Hi,

I've been trying to work this out for a while but have not come up with anything solid that does not require a hack or multiple game objects. I have a line that is made up of multiple points and I want to display all the points that make up the line but at the same time I want them to be selectable.

Ideally I want to have a line game object which renders cubes to show where the points are on the line. Then I want to be able to click the points at any time to be able to manipulate the line.

Thanks
