3ds Max :: Display Coordinates Relative To Last Point When Creating Lines

I'd like to know the coordinates relative to the last entry when creating lines (splines). When creating splines using the line tool, it would be useful to know the coordinates of my current cursor position relative to the last point in an easy way, so I can draw precisely a long line without having to memorize the coordinates of the last point.

Initially, I thought the 'Keyboard Entry" rollout would show the values that reflect what I'm doing visually, just like the rectangle tool for example, or pretty much any other tool, I don't know why the 'line' tool is different but anyways.
