Can we have a tool like a button to click to identify or highlight 100% identical same setences present and wrote by Scalenut in the content?

There are lots of 100% same exact sentences written by Scalenut thus

• A button to highlight those 100% same exact sentences
• A button to remove all other 100% identical same sentences

will be helpful. Having duplicate content issue on page, on same post, is a serious SEO issue.
