Allow installing packages without changing pyproject.toml

[SamoylovMD]

I want to migrate my team to PDM as a default build manager. We use PyCharm as IDE with remote debug server, which works upon installation of pydevd-pycharm package for the specific PyCharm version (more info). Each member of my team uses different version of PyCharm, however pyproject.toml is shared across the team so I cannot add my own version there because it won't work for the rest of the team.

I didn't find a way to install a package into project virtualenv without modifying pyproject.toml. Did I miss something, or is this feature not implemented? If it's not — I propose to add some option to pdm add command to avoid modification of pyproject.toml, much alike there is an option --no-lock for pdm add. Alternatively, maybe there is a way to allow pdm install accept package definitions as argument so it would install not from lockfile but a direct package into environment?

tldr: allow package installation to environment without adding it to shared files.
