Profile from Corridor Element tool

I've been looking for this tool and cannot recall where it is. Isn't there a tool where you can begin your profile and you snap to a corridor element as the starting point? I think specifically of creating a drive C/L alignment and then creating the profile grade for it. I want to begin the profile grade at the EOP of my mainline so that if my mainline goes up or down, so does that begin point of the drive profile. I know I've seen this and I've been searching for the terminology to net some results, but not coming up with anything.

Any help is appreciated before I slowly unravel trying to think of it!
