Pathmapper/ list structure

I have a 40+ list item going into an entwine. Is there a better way to do this without using the pathmapper? or how do I do it with the pathmapper? normally flip matrix would work just fine but my data is to complex for that.

Can you explain what you want to do?
On your initial tree the branches are all long 12 items, and yet you used List Item up to “+40” , with Wrap=false … all those outputs are empty, nulls. It really doesn’t make sense. (26.8 KB)
