would it be possible to add it as an option to the trainers themselves?😉
No, it was done on it's own because halfway through the releases the game devs blocked achivs so it was made as a hotfix. Adding it would to every trainer would cause another re-write (for the 7th time) to each one and Caliber does not have the time for that, and given the amount of work this series has caused, probably does not want to. For which I can't blame him, he only has another million trainer to take care of as well. A solution exists, that is all that is needed for now.
