Firsty-Substitutions are awesome isn’t it! It’s basically a similar train of thought as C and Am7 or Gmaj7 and Bm because they the notes to build them are in those chords too. With sus chords it’s a little bit more obvious than with these but sometimes the fifth or even the root for example can be implied (D7 works as a substitution for Am6 for example (and vice versa))
