Thanks again for the submission! While the initial idea is valid, the current implementation is quite minimal and doesn’t introduce enough unique script logic or scenarios beyond what’s already covered in the repo. Since similar patterns already exist and this doesn’t add much new value, Closing this for now. Once you make additional changes, feel free to re-open this Pull Request or create a new one.
