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!
