A way to do this is to add another “item” to the matrix that can be used to set the [environment variables for the job](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idenv). As a concrete example, see this commit, which adds the “group” item to the matrix, and references `matrix.package.group` to set the `GROUP` environment variable:
