Bloglovin' RSS feed for multisite

Hey,

My bloggers are complaining about the Bloglovin' app for smartphones and tablets, are stealing their traffic. They can't see their traffic on their site, and therefore we can't either.

Then i found this post: http://www.beauty-soup.co.uk/2014/09/how-to-add-read-more-to-blogger.html (please read)
- and want to know if this is possible for my multisite, so every blog doesn't have to do this process?
