Based on your description of the project, I would recommend using a corridor. The specific built-in subassembly that does benching is called DaylightBench, but it's going to search for daylight, not necessarily 20 meters height. You could create a temporary surface using a temporary corridor that uses LinkSlopeandVerticalDeflection and then daylight to that surface using DaylightBench.
Or you could build a custom subassembly using Subassembly Composer.
