In EndNote you can go to Edit > Output Styles > Open Style Manager > locate the style you are using > Click Edit > go to Sort Order under Citations > here change the setting to Author + Title or Author + Year + Title > go To File > Save As > (EndNote will not allow you to change the existing style in EndNote but will always apply the change to a copy of the style) Click Save to save the changes to a copy of the style > close the style window.
