how to fallback source if workspace is not available

[KevinNitroG]

Currently I have a monorepo project. But each subrepos inside (git submodules) aren't published to Pypi.

this is the structure

 packages
├──  cli   <---- cpn-cli
├──  core  <---- cpn-core
└──  docs  <---- cpn-docs

the cli require the core one, and I have set the source of the core in side the cli:

...
[tool.uv.sources]
cpn-core = { git = "https://github.com/check-phat-nguoi/cpn-core/" }
...

Also with the docs, require cli and core

The large repo has the pyproject.toml:

[project]
dependencies = []

[tool.uv.sources]
cpn-core = { workspace = true }
cpn-cli = { workspace = true }
cpn-docs = { workspace = true }

[tool.uv.workspace]
members = ["packages/cli", "packages/core", "packages/docs"]

---

The problem is with the core, cli, docs repo on github themselves, cannot resolve the source of their deps. For ex the cli doesn't know where the source of the core is, without defining the source in cli's pyproject. But, if it the source is defined, then it will override the large's repo source, which make no sense.
