How to attach multiple files to the same reference in endnote and then open any of the attached files from the reference later on?

If you open the record, all the file attachments are displayed in the File attachments field and you can open any of them by double clicking. 

Somthing for the suggestions forum I guess:  It would be nice if the Open file attachment provided a drop-down to choose which one, rather than only allowing one to open the first.
