Intersection cut

Is it possible to add a feature in easel that you can cut at an intersection. I will give an example of a circle with a line going through half way. To be able to cut the circle where the line is intersecting so you can delete have the circle but leave the other half. This may be a feature already but i could not find a way to do so.

Cover half of your circle with a zero-depth item such as a square then combine the two.
