In a Jenkins Job you can select to use git to clone / pull from multiple repositories but it always pulls straight to the working directory so if you have multiple they end up overwriting each other.

What I'd like is a checkbox to say clone to a directory (under the workspace) named for the git repository.

So (when checked) if I had the command as:
https://github.com/jenkinsci/jenkins.git

it would checkout to .../workspace/job_name/jenkins
