List Item set to 0 will select the first item from each branch. Or you can set the value to 0 and reverse the input to get the last value. But as there is always another way to get the same results you can also set the value to 1 and wrap the list to get the last one in this example

If there are two items in a branch, do you want the first or the second?

 

Basically what you need to do is use the [List Item] component. If you use Index=0 then you'll always extract the first item, if you use Index=-1 you'll always extract the last item. If you need control over individual items, then you'll need to generate unique indices.

thanks a lot

to create individual indexes for each branch would need to decompose the tree in several branches, as would?

The tree is already decomposed into several branches.
