title: How to define unique workspace for each branch in Multi branch build Jenkins
body: <p>I'm using Freestyle multi-branch project to define a build for all branches in the project.
  The problem is that if I use "Use custom workspace" I cannot define a path using ${branch} name.
  I would like to do something like:
  Use custom workspace: [dropfolder]\${branch}
  But the ${branch} is not recognizable. </p>
