Bibliography with ... for large number of co-authors

Dear phorum,

I am limited with regard to space of bibliography. So, for the papers with many co-authors I would like to have a reference that inlcude first authot and the last author , like:

Ossandón, T., . . . Lachaux, J.-P. Transient suppression of broadband gamma power in the default-mode network is correlated with task complexity and subject performance. J. Neurosci. 31, 14521-14530 (2011).

However, at least in Endnote5 the only possible option is to have first 6 names and the last name: 

Ossandón, T., Jerbi, K., Vidal, J.R., Bayle, D.J., Henaff, M.-A., Jung, J., . . . Lachaux, J.-P. Transient suppression of broadband gamma power in the default-mode network is correlated with task complexity and subject performance. J. Neurosci. 31, 14521-14530 (2011).

Is there any solution  / workaround to my problem? Is there any improvement in the later Endnote versions? I do not want to upgrade just to find out that there is still no solution.

Thanks
