Use case:
We have our build jobs on Jenkins which show Revision from Git displayed on the build number page. So, that is the latest build version deployed. And as seen in the environment variable list, GIT_BRANCH is the variable which shows us that. So if we could add this environment variable to the list view, that would be helpful.
And seems like the GIT_BRANCH value in the environment variables shows that revision number:
GIT_BRANCH refs/origin/tags/v1.45.0.4

So you are requesting a new column that shows one or more environment variables, correct?
Please provide a use case why you need this kind of column.
