Same problem here and your elegant solution seems to do the trick. However, this raises a follow up question… Let’s say I use the label field to add the asterisk as suggested, does it mean those references will remain ‘labelled’ with the asterisk in my EndNote library? What if I want to cite in another paper one of those references in a context where it does not require the asterisk (ie. not part of a meta-analisys), does it mean I need to ‘unlabel’ the reference? Seems like a tedious and error prone process… Still new to EndNote, any suggestions about this?
