Save collections to local storage via command on startup

Is it possible to save all collections or collections based on publish on app startup? I would like to load everything once the app starts

The issue names no files, tests, or entry points. Start by tracing GroundDB collection initialization and the application startup path, then determine how publish-based selection and local persistence are currently handled. Done means a documented, tested way to load all collections or the selected published collections when the app starts.
