Git Flow Finish Feature with Fetch

Hi, 

For the community that utilizes Git Flow for SourceTree, I've seen a demand for the functionality of also being able to finish the feature on remote as well as locally. 

SourceTree currently finishes a feature by using 
git flow feature finish "featurename" 

But there should also be an option for sending the same command with a Fetch as well, so that it pushes the feature finish to remote. 
git flow feature finish "featurename" -F
