endnote online needs to allow more than one folder of references so we can maintain separate libraries

Biomedical researchers need to have a way to keep separate libraries while still being able to sync libraries online.  We often surpass the limit on numbers of references in a single library, and to keep ourselves organized we need to be able to maintain separate libraries, just like we would on the desktop version!  Please fix this ASAP, because once our libraries are merged online, we can never go back and separate them.  This is urgent request!
