Hello! Unfortunately there is no customization yet for project folders: Projects and user settings are saved in Per-user application data directory, which by default points to:
%APPDATA% on Windows
$XDG_CONFIG_HOME or ~/.config on Linux
~/Library/Application Support on macOS
example in Linux:
~/.config/drafft ls -lh

I agree it would be nice to make it more portable and customizable! Hope it helps!
Meanwhile a (rather cumbersome) workaround you could try is using exports. but its not what you are asking for.
