Problem saving .ipynb from Littlest Jupyterhub to cloned git repo folder

I previously rendered .ipynb files in GitHub by cloning a git repo my_project, saving .ipynb files directly to that folder, i.e. /git/my_project/file.ipynb, then pushing my_project. Now I’m collaborating using Littlest Jupyterhub and can only save files under a protected user folder under home/jupyter-admin.

Is it possible to change the savepath to e.g. /home/git/my_project despite home/jupyter-admin seeming to be the highest possible folder?

Is there a better way than saving .ipynb files directly to a git folder repo, then pushing it, for easily rendering and changing .ipynb-files from Littlest Jupyterhub to GitHub?

Thank you
