Use of Term Lists to assign an Impact Factor to every reference of a library

Hello,

This discussion helped me to update the journal names and corresponding impact factors in the term lists. Now, I wanted to select all the journals in my EndNote library which have impact factors greater than a certain value. Is there any ways to add the Abbreviation 1 (now my impact factor) in the EndNote fields so that I can sort all the journals based on the impact factors. Is there any better ways of doing this task.

Thanks
