How can i have separate targets of poetry_dependencies when in a single pyproject.toml file i have sections of grouped dependencies like [tool.poetry.group.mypy.dependencies], [tool.poetry.group.flake8.dependencies], [tool.poetry.group.pytest.dependencies]. I understand we can do this in python_requirements by creating separate requirements.txt like files and putting them as source for python_requirements. I want to restrict to one way of defining dependencies and that in pyproject.toml file
