Feature Request

It would be useful to be able to freeze the version of a dependency at the same time as add. Some dependencies can be volatile, and even with the expectation that a minor revision should not chage the interface of any dependency, to certain projects, this risk may not be tolerable. Whereas we can already manually edit the pyproject.toml file to achieve this, an option to the add command to by default add a specific version 3.1.4 rather than ^3.1.4 or no version at all, would be useful.

Being able to do this retroactively could also be useful, using, say, poetry freeze numpy, which will freeze the numpy dependency to its current version in the lock file.

You can already do this.

poetry add pytest==6.2.4

for example.
