Water - Ocean Spline Falloff

Version UE5 Alpha:

Is there a way to change the falloff on the ocean spline at just one of the nodes in the spline instead of the entire thing. I want to have a sharper ocean cliff face at just part of the spline.

I found I can sculpt the terrain into the sharp cuttoff I was looking for by making sure I select the water layer when sculpting landscape. (Or by doing my sculpting on a new layer above water in the terrain sculpt section
