All-caps title words converted to lower case by title capitalization

I set the title capitalization format to “headline style capitalization” for my bibliographic output style.  This worked great except for the titles of articles that include some words in all-caps.  In this instance it converted the word to lower-case, except for the first letter.  For example, it converted EQCM to Eqcm.  Is there some way to maintain all-caps words in article titles?  Thanks.

Add them to the Edit>Preferences> change case list. 

Luckily in the sciences, I have never run into a journal that requires the titles in anything other than the way they have been downloaded from pubmed…
