Usability of the new BlendSrf

Ok, I have an issue with the way the new BlendSrf works. Even with adding shapes, I find it difficult to make good blends, even between simple surfaces, it requires additional input even between single span surfaces, which I find strange. With more complex cases, it becomes hard to figure out where to even place additional shapes.

It really slows down work when you have to Sweep2 or MatchSrf the result of every blend.

Could i get some feedback, maybe what am I doing wrong, or could the simple sweep option be made optional?

Thanks for this post and the file. I agree that the simple blend surface should be an option. I filed
