Same action on every item in a list

Hello everyone, hope you’re having a good day.
I’m almost sure this will have a simple solution, but I couldn’t find it anywhere. So here goes:
How can one apply the same action to every item in a list?

I’m trying to join all the curves in each item of the “flattened by 1” list in the image into seperate polycurves.
Thanks a lot!



Hey thanks :slight_smile: totally worked.
