Would it be possible to upgrade unit to more than level 9? to 20 for exemple? Mostly for manufacturing, purchasing and selling units? Of course with a huge cost scaning on training to not unbalance the game.
Just that on some products i have to dedicate 2 shop floors for 1 product in really high demand and with 6 shops doing the same, i have no more space for diversity of products

In script you have a scaling modificator for factory, could you apply it to farms? WAREHOUSES!!, and maybe shops?
An option to UPGRADE a factory from small to medium, medium to big ,etc would be great, better than to destroy it and build a bigger one with low lever training units :p
My best regards
