feature request: automatic creation of missing notebooks for use after git clone

[itcarroll]

The README section Collaborating on notebooks with Git
nicely describes how to create the .ipynb files for .py notebooks under version control. Thank you for that documentation. The actual process is a little tedious if you have several notebooks and the .py notebook files are somewhat buried.

For projects with configuration files that shows where .ipynb notebooks should be, would it be reasonable to have a shortcut to generate any that are missing? One possibility: execute jupytext --sync with no additional arguments in a project with a jupytext configuration file.
