Hard to do globally for author names, since they are all different. Just have to bite the bullet. I fix 'em as I use them.
The journal names link provided by Tony uses the terms list, but it won’t change your records, but as long as your output style is set to pick a column (full name or Abbrev 1 usually), it will be corrected in the output bibliographies. – Just make sure to add the the versions in a later Abbrev column so they are all resolved correctly!
