Sometimes I import multilpe references, e.g. from a special issue of one particular journal. Then, if Endnote does not recognize the articles and completes the references automatically (which is mostly the case), I need to edit the imported articles manually.
This would be much more convienient, if one can just mark the references and asign certain attributes (e.g., journal, issue, volume) to all of them just once. For instance how it is possible in iTunes. You might want to check out how it works there and just apply it the same way to Endnote. Thank you.
