  <p>As you can see automation rule made that field blank (I know why, I've resolved the problem, I just want to bring that value back). I bet there is a way to achieve that using JSON, but I'm not a specialist if it comes to that language.

  Do you, by any chance, have some experience with it and maybe you could help me? :)</p>
