General Question Is there any way to flatten user-made base runways so they don't undulate?

Is there any way to flatten user-made base runways so they don't undulate with the underlying terrain mesh? Thanks!

EDIT: I just found about tileedit's "rudimentary capabilities for editing elevation data", but is there any other method?
