New zoning tool - replace a ground layer

We need an additional tool besides mining and dumping - a replacement tool. Currently, it is very inconvenient to replace a layer of rock with a layer of dirt, for example. The step-by-step process requires a lot of time to manage and often leads to "loops" if dumping occurs next to mining.
Another good idea would be to add "zone-less mining forces" that can mine areas outside of mining tower zones. This would be useful for small fixes, where a player needs to fix a small patch or bury a pipe, for example
