remove only internal links from articles

Hello, I want to know how I can do this with your plugin. I always use wpautomatic and start using your plugin because it seems very good to me but I can't find the option how does wpautomatic do this: Just remove the internal links from the post and leave the links external links and add rel no follow blank to the external links so that they open in a new window and do not pass authority, can you tell me which option I should check to do the same, thanks
