Driveway End Conditions

I have set up a template for a driveway on a corridor I am working on. The corridor itself has ditches on both sides, and ties to existing terrain.

I am looking for the best option when it comes to tieing the end conditions of the driveway into the modeled end conditions of the corridor.

I have tried in the template editor to have the end condition to target a certain feature definition, that I then manually have to draw into the 3d model. It is a microstation line that I have going perpendicular to the eop of the corridor, and the ditch lines, basically creating a profile of where I want the EC of the driveway to tie into.

This works, but is time consuming and when it targets a feature definition both horizontally and vertically, I have no control over the slope of the EC.

I was hoping there would be an easier way that I have no discovered.

Thank you for your time and help.
