The creation process for folders that get generated by the Toolkit schema, can be customized in the
process_folder_creation.py core hook:

.../config/core/hooks folder and then modify it there. Or if you’re on a distributed config then you could take a copy from the GitHub repository or your bundle cache.

ensure_folder_exists.py core hook:
