Format notebook at once or automatically calling %%black?

[David Slochower]

Any thoughts on enabling the option to format multiple (all...?) cells at once with %%black?

@tobinjones has built a Jupiter extension to achieve the same https://github.com/tobinjones/jupyterlab_formatblack Please take a look and close this issue if you think that suffices your need.
