It would be great to find some way to get rid of this tedium for very advanced worlds. Possible ideas..
- An improved construction-only roboport with a massive range - i.e. 10x the current roboport.
- An advanced, roboport-independant construction robot which is tasked with a single action - i.e. go clear all trees or landfill all water in a 200x200 radius.
- A construction robotport version of the spidertron that can be given a route and sent out to clear and landfill
