Why would you want to provide the benefits to your competitors? Anything in json covers for ALL studios in the game, so you are actively screwing yourself over and losing any kind of advantage.
Just save-edit your own studio. And if you can't (but you can write and read in English, so you have no excuses here), then there is always the tedious search for related float values for specific upgrade.
The game meanwhile stopped receiving any updates since the D-Day, so... yeah
