I don't know whether this has been asked before, but is there any way to use the IEEE style where instead of the in-text citations being [1],[2],[3],[4] they would be [1-4]?
IEEE requires the style like that and it was a change introduced earlier this year. See here for an explanation.
While we'll certainly have different numeric styles that will match what you're requesting, if you're required to use the IEEE then you should stick to our IEEE style implementation.
