Trouble lofting pairs of curves

Hello,

This is my first time posting in this forum, hopefully somebody can help me! I have a grasshopper definition (attached) in which I have two sets of curves that I am trying to loft together so that only each corresponding pair of curves gets lofted. When I try to loft the two data sets together, grasshopper wants to loft everything together into one big loft instead of many separate lofts from each pair of curves.

I seem to remember that the use of flatten and graft usually solves this kind of data stream problem, but I am using a very early version of grasshopper (I believe v6.0058) that doesn't seem to have any flatten or graft commands. Is there any other way to accomplish this in the older versions of grasshopper??

I unsuccessfully tried installing a newer version of grasshopper, but with my older rhino version run on parallels on an almost outdated macbook, this was the only version of grasshopper that I could successfully install so I'm trying to work with what I've got.

Thanks in advance for any help you can offer!

I don't remember when data-trees were introduced, but if you don't have access to a component called Flatten, then your version probably pre-dates trees and you cannot organise a single list of curves so that loft only operates on sublists.
