What I'm trying to do is create half gauges, but when I create half gauges the size of the control is still setup for a full gauge and has a lot of extra space on the below the half gauge, when I try to resize the control it just shrinks my half gauge, is there any way to resize the control to fit a half gauge?

Attached is an image of what I am talking about, the blue line is where I could like the bottom of the control to be, but without resizing the gauge.
