Hide / Do not Index Steemit Posts on Google Feature?

Hello Community Members !

It would be nice if there was a feature (button) to Turn Off or Turn On indexing of Steemit Posts on the Google search engine.

Like I have so much content on my blog PrakashGhai that I want to post here but I don't as it affects my google ranking for posting duplicate content.

If there was a feature to turn off Google Search Engine Indexing on Each Steemit Profile or Per Post, that would be really cool feature.

I remember such kind of feature was available on Tumblr long time back (now removed)

Thank You
