How to modify branches in a data-tree?

[trc940825]

Hi everyone,

I’m trying to modify a data-tree, which has 3 layers of branch for example:

Then, without changing the written program, I would like to merge those branches in the second layer, which means I want the result like this:

I tried to make it by using “Path Mapper”, But the result is not what I want：

So How can I get the results I want?

Thank you!

a little bit hard coding but it does the job

I’d recommend managing this at the source where the data structure is generated

Thank you very much Will, That works!

One more question, which is the meaning of

“path_index-a*4”

I’ve never seen this in any tutotial, could you tell me where can I learn that?
