Output style with first, second and last author


I want to have a reference list with only the following author names: first, second et al and last author.

I was able to add the first and second but I can’t figure out how can I add the last author too.

Any ideas?

Thank you!

This is not currently an option with Endnote.  The best you can do is if 8 or more, 6 … last (see attached).  You will need to ask the developers (in the suggestions forum) to add a more flexible option.  I think someone else may have already requested it, but modification requests like this often take months (if they are popular) to years or never (if not reinforced by others).  

Thanks for your answer!

I will give it a try in the suggestion forum, it would be really helpfull to have such a style.
