[Feature Request] Manipulating displacement vertices

[MARK2580]

I don't know if it's possible, but I'd really like to see the editing of the vertices directly by the displacement of the object, and not by the brush from which it was created. Something like vertex manipulation in a 3d editor for example. At least make them move around the grid and stick to other vertices. That is, I want something like free manipulation of one specific vertex (the appearance of a gizmo). The movement of vertices only along one of the 3 axes is terribly inconvenient for fine tuning.

As an example, editing displacement using the wallworm script and the final result in hammer.

In your scenario you might just be better off stretching the displacement under the ground instead but this would still be a valuable tool. It'd be nice to not have to rely on external tools like Wallworm to get decent displacement jobs done but we're still far off from that.

Under the ground, you will see a gap between the brush and displacement. I'm interested in the perfect joint, in this case only wallworm will help, but it breaks the map very often.
