title: Version or Found in build dropdown
body: <p>I use Team Service online and I want to automatically add a build/version to a list when a build or release is succeeded. This list I want to use as field in a work item. The already available field "found in build" is only filled in tfs on premise, I found in the manual. I want to add a custom step in the build or release task to add this version to the list. Is this possible?</p>
  
  <p>I have searched the internet and I can only find tips for the on-permise edition.</p>
  
  <p>Other options or tips are also welcome.</p>
