Classic chord progressions like "Line Cliché"

Thanks for a great product. Something I’ve missing is chord progression examples from real songs in the main>songs view… I’m guessing the reason is legal for not having well known songs as examples?

Is it possible to have parts of a songs like the “Line cliché” part or Augmented steps part of a song?

I’ve never used the ii-V-I-vi notations that much all though I understand it. For me it would be much more valuable with examples from real songs. Not the whole song but as I mentioned just an intressting part like the “Line Cliché” for example.
