Within the Table Editor tool, provide the designer the ability to graphically edit the profile while simultaneously locking any particular VPI or grade in proximity to where they wish to make a change. This was an awesome feature in Vertical Geometry Builder within Road Tools of GEOPAK. Why was this functionality taken away in the first place? Please put it back!
Suggestion is to put graphical edit tool similar to what is available in Corridor Object menu into the Table Editor to allow a user that enhanced flexibility when designing. You might say that you can simply move the VPI's and handles up and down in the profile window using the Civil Rules but what it does not provide is the ability to lock preceding or succeeding geometry along the vertical alignment.
