Add "no follow" to sitelinks, how?

Hi guys. I want to add the "no follow" to some sitelinks in the main menu, but i don´t know how to do that. I see noting in the admin, should it be added in the code? Thank you guys!

Hey Rebelion,
Have a look at this plugin: [-link-]
Hopefully this is what your looking for.

Downloaded and intalled some minutes ago. Easy to use, but I think it´s not the best way to me.

I need to add nofollow to 2 sitelinks, it´s possible to do that with this plugin? If I add my domain to Omit Domains none of my links will have the nofollow.....for me it´s impossible to add only certain pages because I have about 600 content pages, custom pages, etc

Thank you for the info, I´ll keep the plugin for a while to see how it works.

Best!
