Hello,
Can’t seem to find a way to add the string “Main Model” to every sublist that only contains one element.
Looking for an end list that whenever item at index 0 is “Main Model” it appends another one at index 1 at that same sub-list level.
All sub-lists will end having 2 items only.
Any ideas?
Thank you
Maybe this python script can help you!
thank you
but still not working… 
You have to use the python script after your “code block” node shown in your first screenshot 
many thanks @tiagocorradi.
Works a treat 
Hi there,
I think you could do the same without using Python nodes:

very slick, @Manel_Fernandez.
I like it!
