Merging EndNote libraries and maintaing group sets

Hello:

I have a user suggestion for EndNote, in regards to merging 2 or more different EndNote Libraries.  I think it would be really useful to have the ability to merge 2 diffferent EndNote libraries, and maintain the integrity of the pre-saved group sets from both libraries.  Right now, I have to make one library the master, then create each new group into the master and drag and drop references from the 2nd library into the master library.  It would be great if I clicked on import Endote Library into an existing library and the group sets from both were all shown.

Thanks for your consideration.
