Safari - Easy way to open a link in private window? Is there an easy way to open links in a private window in Safari in OS X?

With this, I mean copying the link and pasting it in a new private window not as being easy.

In Chrome and Firefox, you can easily open a link in Incognito/Private mode, right clicking on the link and from the context menu, choose Open in an incognito window. This is a feature that I use quite often in my browsing, but I'm trying to switch to Safari because I noticed that Chrome uses more battery and read some articles about it too.

I would really appreciate it if you tell me of any way to add an option to the right click context menu in Safari to open in a private window, or a keyboard shortcut so that you click while pressing some keys and it opens in private mode, or maybe an extension that adds this functionality.
In Safari 9.0 (El Capitano) you can right-click on the URL while holding down the option key and you then have the option to open the URL in a new private window. This option is provided from regular or private windows, unlike what appears to be the case in previous versions of Safari.
