set conda-pypi-map globally?

[Ralle75]

We have a isolated network that has no access to the internet. We have been using pixi on this network for a few days. Basically, everything works. We have a conda-forge and pypi proxy that works really well.
We can run pixi add python, but when we run pixi add —pypi numpy, for example, we get a timeout. I found out that conda-pypi-map is trying to connect to https://conda-mapping.prefix.dev/, which of course doesn't work.

I have now provided a mapping.json and entered it in the project-related pixi.toml via conda-pypi-map. That works great. Unfortunately, I can't tell all of our scientists to add this entry to their pixi.toml.
Is there a way to set this entry globally, similar to other entries, for example in /etc/pixi/config.toml? All attempts have been unsuccessful so far.

I think this is already tracked in #3199
