Reimport heightmaps and weightmaps for world composition terrain.

Hello all!
I’m experimenting with world composition feature. I imported the 16 different heightmaps, which worked just fine. However now I want to tweak some settings in the height and weightmaps but I’ve not found a way to easily reimport these maps. Unless I load each section seperatly and load the heightmap again as you would do on a single normal terrain.
It’s very important in my workflow that I can easily iterate on the terrain and push those changes to ue4.
The documentation mentions this part way at the end. But I can’t find this option…

Any help would be greatly appreciated!

I’m in the same boat. I dont think this option exists any more and there’s no information on how to do this now outside of writing your own system or importing each heightmap manually in the landscape manager.
