Cliff building mechanic is too limited

[Schattengaenger]

Hellow fellow hearthlings,

I really enjoyed the fact Embankment Scaffolds where added, but it is in my opinion far to limiting in what you can do with it.

1. you can only generate cliffs by adding dirt in front of it, meaning digging some sort of trench with the walls lined with cliffs is almost impossible.
Yes, you could theoratically dig it out wider and place the scaffolds into the ditch to make the sides into a cliff,
but that isn't always a viable option when space is limited.
2. While making an outward corner is no problem at all, an inward corner is not possible.
The issue being you cannot have one scaffold support two sides at once and it needs to be built on flat ground.

Maybe for the second problem some sort of corner post would work to change that.
