Working with lists

Hi, I have 6 curves that are being divided by the same number, 20 for arguments sake.

What is the most efficient way to select the 0 item (point) of each divided curve and draw a curve through the points, then the 1 item, then 2, and so on? Without creating 20 different List Items?

This seems to be a problem which I run into often and cannot believe that this is the best way. So, please enlighten me if possible.

Thank you,
Adam
