I turned off several Wood plots and turned on all my Stone plots. The thing is.. the Wood plots live in a region that yields Grain, I don't have to import it. The Stone plots live in different regions where I do have to import. Is there a way to add import charges, to see if they are really loss making with these additional costs.

To disable them, I harvest, then remove the power core.

Thanks for your interface and all the work you have done, it's very handy!
