Anyone know how to create an Outlet so a Niagara fluid simulation does not fill the container?

For a Civil Engineering course I have to do a fluid simulation of water coming out of a hose and what happens when an object blocks it’s path. I created a Niagara 3D Hose water simulation and it works perfect except one issue. The water emitted from the hose eventually fills up the whole volume. In Blender you can designate an object as an Outlet to the water can be removed from the volume, like a hole in a bucket. Blender is too slow for my needs. So I am using Unreal Engine. Any idea how to achieve this? I’ve been searching but so far no luck.
