Building roads on this game is horrible

It should be way easier than this. You have to click the engineer unit, then click the terraform button, then click the road button, then click where you want the road built. And you have to repeat that for each engineer, every single turn. It makes me not want to build roads at all. It should be two clicks only, or three at most. And there should really be a means of automating roadworks where you plan the route first and the selected engineer unit builds the road without bothering you until it's finished.
