Hello, I wanted to create a custom HDA to paint terrain height and vegetation, etc, but I can't find a way to undo my last brush stroke. It's finicky to use when painting terrains without undoing. Did I miss something? Is undo supported
at all?
Additionally, it is also impossible to save the progress in the middle of painting and continue it later. Because after you save and reload the scene, the hda becomes un-editable. You'll have to rebuild the asset to make it editable again and lose all the progress.

So these two setbacks make the terrain solution I'm working on unfavorable. Any workarounds?
