Hello!
I have found very gentle and beautiful solutions for filtering lists if they are composite ones, but i am struggling to build a filter for a-non composite list which has 5 levels of detalization.
Hierarchy looks like this:

And in Anaplan it looks like this (client does not want a composite list, he wants it in this way)

My goal is to be able to have a filter like in the picture below

Would be grateful for any ideas/help.
Thank you very much in advance!
Anton
