UI Slider Chop instead of Scale

Hello,
Back in NGUI there used to be a option(can't remember the name of it) to make the slider fill area chop off by fill amount vs. scale by the fill amount.
1) Is there a similar feature in Unity UI?
If so
2) What is it called?

My example is I have a game where the shape is not a rect it is a star and I would like to cut off the star to show a level of completion for each element rather scale and have the full star just shrink toward one side of the background.

Hope this makes a little sense.

Thank you for any help,
George

image.fill* maybe

 

Nice. For those who don't know like me this also works with a slider. Just change this setting on the fill image and you will get a chop instead of a scale with your sliders.

Thanks rakkarage!
