I don't think you can. But I can advise you to use Atom, Sublime Text 3 or VSCode. They automatically save your code so that if the editor or your system unexpectedly shut down or crashed, you wouldn't lose your progress. I can at least say that for Atom and Sublime Text, haven't tried VSCode for similar problems.

EDIT: And use git. Create a private repository for your project, so that you can also keep track of your changes, and avoid loss of code.

Don't use pawno.
