If it’s possible to combine plain and hierarchical view together?

I'm facing the issue of data representation. On the same page, it's possible to view both plain and tree structure. It's ok (tbh no, but we can live with it for a while), but when it comes to new object creation it feels like a duplication as it appears in two places.

  1. As nested object
  2. As an object in the list

Question: Any idea how to solve it? How to get rid of the feeling of duplicated object? Keeping the plain and tree structure on the same page?

Thanks.
