# How do I make a shaped fluidSurfaceActor in UDK?

I'm trying to make a fountain for my level in UDK. I've made the base of a fountain by using a Cylinder build and now I'm trying to put water in it. I want to use the fluidSurfaceActor but I notice that it's square, while my fountain is a cylinder!

Is there a way I can change the shape of the fluidSurfaceActor to fit the builder brush shape or is there another way to do this?

Here is a picture of what I'm talking about:
