Django setting up view to change settings.py one-off settings

I'm nearly done with my Django app and I was wondering if it's to create a custom page where the app user admin will be able to cahnge one-off overall app settings like language, timezone, currency, URL slug, app limits (e.g. Max number of xyz, default abc etc) etc Is this possible? Feel like I'm missing a trick here. Any advice or resoucrces would be great.
