Flipping Triangles

In other DTM software, there are tools to allow you to select a dagonal leg of two adjacent triangles, formed between four points, and to flip the diagonal to the other two corner points.

I could have sworn that I read in an InRoads Readme that such a tool was now available in InRoads, but I cannot find any reference to such a tool.

I know I can edit breaklines to do this, but this tool is simple and quick. The same cannot be said about adding and possibly breaking up breaklines to accomplish the same thing.
