Multiple reference at a location

Hi,

I have built my reference at the myendnoteweb site and I use the plug in in word for inserting references and building the bibliography.

At various places on my manuscript, I have more than one reference to cite. Example, [1][2][3][4] etc.

I want to show this as [1-4] instead of the four number listed separately.

Is there a way to do this? I dont see any options in the Endnote toolbar in word. I am using the IEEE style.

Please advice.

Thanks
