Hey Ludi,
The that we use, is installed system wide with the file in the Software/Python folder. All the programs that ask for, are given the library that was installed from there. If you only want to change the header in one project, then I would suggest you to copy and paste the updated library in that project. When you are satisfied with the updated header, you should run the in the same folder as the updated library and it would make the updated as the default library system wide.
