Add option for "--set-upstream origin" for untracked branches

When I create a local branch (either directly or with the git flow feature) and then push it, it is not tracked and I have to add tracking separately. I would like an option to do this automatically (similar to "git push -u origin" on the command line)

I have tried checking the preference "Automatically set up tracking for new branches", but this doesn't help (what does this anyway? Couldn't find it in the online manual)
