Feature Request

Hello everyone, I'm a python developer live in Mainland China. As well known the network connection is so bad in my country that we cannot connect to the official PyPI repo directly sometimes. So most of us usually some PyPI mirrors in our region (like https://mirrors.aliyun.com/pypi/simple/, it's deployed by AlibabaCloud) to get a fast and stabilizing network connection. PIP gives us a way to set the index globally using pip config set global.index-url . But I cannot find related config items in Poetry.
Okay, I know what you want to say, I know I can set repo info in my pyproject.toml like this.

[[tool.poetry.source]] name = "aliyun" url = "https://mirrors.aliyun.com/pypi/simple/" default = true

But it will cause some tricky problems. If I have some workmates in other countries, they don't need repo mirrors to speed up service, even it will make them cannot use PyPI repo (thanks to stupid GFW), or we need to use Github Action as our CI service, they all don't need this config item. So I think the PyPI repo URL should not as a project config in my project repo, we need a way to set in our dev environment and use it for all projects. Thank you.
