Indexing Menu Titles

in SS 7.1 Is there a way to prevent a Navigation Dropdown title from being indexed by Google and  warning being received. I have looked on line and all the methods seem to suggest Folders or Inserting CSS  or using non index tags in the page headers. I can not see any options  from the gear wheel settings of  the Nav title in Pages except the /url  etc

Do I just have to accept the Google warnings

 Thank you
