title: How to reuse pyproject.toml in monorepo with Poetry?
body: <p>There are multiple projects in my monorepo, which has package management via Poetry individually. For instance,</p>
  <pre><code>monorepo
  ├── a
  │   └── pyproject.toml
  ├── b
  │   └── pyproject.toml
  └── c
      └── pyproject.toml
  </code></pre>
  <p>Each project has its <strong>own</strong> sessions for <code>[tool.poetry.dependencies]</code> and <code>[tool.poetry.dev-dependencies]</code>. However, they did share huge amount of common configs such as</p>
  <ul>
  <li>[tool.taskipy.tasks]</li>
  <li>[tool.isort]</li>
  <li>[tool.black]</li>
  <li>...</li>
  </ul>
  <p>My question is how to define common configs which could be reused for monorepo projects?</p>
