Hello,

How can I entwine the branches and still keep the data structure as shown? Is the only way to do this through python?

I tried with the path mapper, but no luck.

how the data is gathered seems relevant

Thank you for the replies.

So while having only two branches in each input the problem can be easily solved, but what I have is a situation where there might be more or less branches in each list. If that makes sense. I basically want to do what you are showing in your picture, but where the number of input lists can vary.

I just realized that your second one will work perfectly for what I am doing. Thank you. 🙂
