Wondering if this is possible; to have market goods automatically bought/sold x amount per turn. I imagine it would be a ton of work but it would help reduce the tediousness of the market.

I'm afraid that this isn't possible BUT



it should be possible to make building which costs X amount of resource to build (not production) and give some dust/production/approval.



Annoying part of that would be that it would look awful (basically for god only knows why all buildings go to same main address and after that to sub address... afaik that causes messed up situation where you can't spread those nicely to different tabs unless you change hardcoded values).
