Hm, perhaps you misunderstood. I mean the first author and last author surnames. Here is my Rename PDF format which if you have 5 authors produces the first and last author with an ellipsis:

So an article like:
Roach, N. W., McGraw, P. V., & Johnston, A. (2011). Visual motion induces a forward prediction of spatial pattern. Current Biology, 21(9), 740-745. doi:10.1016/j.cub.2011.03.031
becomes a PDF named:
Roach … Johnston (2011) Visual motion induces a forward prediction of spatial pattern.pdf
