The idea has been suggested many, many times. An example would be the current third thread of Closed Suggestions board, among others. But it cannot be implemented at the moment (or probably for a while).Devs have explained that it is hardcoded to engine or something, so it would require cvet, the creator of the engine, to make changes to the FixBoy mechanics. And he's busy with other things.
But they do have the ability to make new functions to the game. Why not ignore the current fixboy and create a new one, just a suggestion.
