Ramp digging tool

Adding the ability to make ramps easily, you drag the ramp from the start point to the end point, and the tool automatically adds dump designations or mine designations based on what is needed to create the ramp.
And to build further on this, add a tool where you designate a mining-and-fill square, where you could choose the fill type. So say you designated the mining squares to be dirt, and your miners would remove any material that was not dirt, and your truck would refill the square with dirt.
This would make it easier to landscape and create things like beaches, pastures, etc.
