### Describe the request The Arduino IDE allows customizing the default ino file with the `arduino.sketch.inoBlueprint` as mentioned [here](https://forum.arduino.cc/t/how-to-edit-the-file-new-sketch-sketch-not-examples-01-basics-bareminium/1059543/2). It would be nice to have an equivalent version in arduino-cli when running `arduino-cli sketch new`. It may also be worth considering an option for a template sketch directory instead of just a template ino file. ### Describe the current behavior When running `arduino-cli sketch new <project>`, the same ino file with an empty `setup` and `loop` is created every time. ### Arduino CLI version arduino-cli Version: 0.33.1 Commit: 347bfeb0 Date: 2023-06-30T15:32:47Z ### Operating system macOS ### Operating system version 13.4.1 ### Additional context _No response_ ### Issue checklist - [X] I searched for previous requests in [the issue tracker](https://github.com/arduino/arduino-cli/issues?q=) - [X] I verified the feature was still missing when using the [nightly build](https://arduino.github.io/arduino-cli/dev/installation/#nightly-builds) - [X] My request contains all necessary details
