Import sort: automatically detect third party packages with same base package as first party

[ivan94fi]

Hi, I have multiple python packages with the same first name, for example company.package1, company.package2, etc.
When in company.package1 Isort automatically flags company.package2 import as a third party, while Ruff detects every package starting with company as first party, changing the sort order.

If I use the following configuration:

[tool.ruff]
src = ["src"]

[tool.ruff.lint.isort]
known-third-party = ["company.package2"]

then company.package2 is correctly formatted as a third party package, but this is not scalable as I have many of these packages and I would need to configure every package differently and update every one with every new package created.

I also tried setting known-third-party = ["company.*"], but this makes all company imports as third party, even the first party ones.

Is there some option to configure Ruff the way I need? Thank you.
