Mine control tower to be able to set to automatically mine resources in its area

Allows the mine control tower to automatically task diggers to mine the available pre within its area. Can be toggled on/off. Let the mine control tower actually control the mine.

I like your idea to initially set the excavators, to the most present ore present in its initial selection area as a QoL, but I often change the area boundaries and and often towards the end there area other ores in the area I don't really want. I would not want it to change because there is more of some ore in an area, or sometimes toward the end, I am going for the stone/dirt and there are trace ores all over the place, don't want it to change just because I changed the boundaries.

That would be rather difficult given some ores are deep or next to other ores and you need to keep path for your miners. Also unsupervised mining can undermine some buildings.
Also i do not know how difficult would be to write that logic to setup proper mining area.
But setting mining designations is part of this game, i would not change it.

I'd love something like this!
I know that some players love the 3D terrain deformation aspect of this game, but to me it's just a chore, having to every so often notice that all the voxels are dug out (no, the Alerts system is not useable) so I have to go designate new ones, while worrying about digging too close to the ocean and so create a flooding event that is, in practice, impossible to recover from.
I LOVE reaching the state where I can import all my Coal, Iron and Copper Ore, so that I no longer have to dig down below height 1.
Auto-designation at mining sites would be amazing, make the game more fun, less of a chore.
