Retrieve Multiple Thread Node Output

Good morning,

we want to run a thread marking the multinode option, the problem is that for every time itere has to return some data, right now although we have it as a list in the parent process, it is only staying with the result of one of the iterations we imagined that something like this would happen since an append is not made when retrieving the result. We wanted to do it this way because the thread has to run for several registers and it takes time, so to make it a little more efficient we came up with this but if we cannot retrieve the result this option is useless.

If you can't do it like this, something else occurs to you.
(The process is synchronous)

Greetings and thank you
