Number range for consecutive citations separator (en dash versus hyphen)

My style sheet says that that for a number range for consecutive citations I should use an en dash to separate the two ends. i.e. [15–17],  not a hyphen  [15-17] which seems to be the default settings in Endnote.  Is there a way to change this in X2? X3? I looked through the documentation, but was unable to find anything.



Endnote cannot do this, but I have never had a journal complain about it.  Their in house processing should be able to handle this one.

However, one of my colleagues routinely does a search and replace on the page field of his library, and he says he has never had a journal that complained about n-dashes in the reference list, who didn’t require them.
