title: merge without merged branch commits history sourcetree
body: <p><img src="https://i.stack.imgur.com/1a6nk.png" alt="enter image description here"></p>
  
  <p>I need to merge a feature branch into my master branch in SourceTree.</p>
  
  <p>Every time I merge the feature branch, I see in the master branch commit history all the feature branch commits history.</p>
  
  <p>I want to merge the feature branch into my master branch and in the master branch to see only one commit added, the 'merged with branchName' commit, that lists the files changed.</p>
  
  <p>I had that option in smart git, can it be done in SourceTree? How?</p>
  
  <ul>
  <li>A: Commit done in the master branch</li>
  <li>B,C: Commits done on test_branch branch, shown in the master commits history (these are the ones I want to remove from my master history) </li>
  <li>D: The merge commit (I want to keep this one)</li>
  </ul>
