Is there a function or method for controlling feature line elevations such that I could tag specific points along the line as the controlling elevations and let the others assign their own elevation by assuming a constant grade between them? I'd like it to be able to remember which points are the controlling ones so I wouldn't have to keep re-selecting a range of points each time.

Yes I know I can select a range of points within the elevation editor and flatten the grade between them. Its too tedious.

Yes I know I can use the 'set grade/slope between points' button from the edit elevation ribbon. Again, its pretty tedious and time consuming.
