RSP Tutorial Notebook setup

Hi, in the UK DAC, the RSP launches with tutorial Notebooks pulled from Github via the values YAML file:

controller:
  config:
    images:
      source:
        type: "docker"
        registry: "registry.hub.docker.com"
        repository: "lsstsqre/sciplat-lab"
    lab:
      env:
        AUTO_REPO_URLS: <github URL>
        AUTO_REPO_BRANCH: <github branch>
        AUTO_REPO_SPECS:<github URL>@<github branch>

The contents of the pulled folder are read-only (permissions bits: -r–r–r–). Some users are finding this counter intuitive as they can’t “save progress” during a tutorial, or make their own Notebooks (reporting “Save Untitled.ipynb, permissions error”).

So, my question: is it possible to make additional Notebooks added via AUTO_REPO_URLS, etc, user writable?

Thanks,
Dave
