Override text box restriction?

[Thalassicus]

A text box replaces any value I enter over 100, with 100. How can I override this?

 

I'm attempting to scale skill-trainer maximum values to match a different skill progression rate, where skills range up to about 200. I changed iTrainingMasterSkill to 150, and now I'm attempting to do the same for every master skill trainer. I used to do this by manually deducting gold and adding skill points via the console, and would like to create an in-game approach.
