I may need to look into this myself. I asked my FC about how to heal people outside my party (because once in battle mode, locking onto random friendlies is no longer available, only enemies). They suggested the use of macros. But this filter option sounds just as good too! I'm copying/pasting this topic onto my 'FF faq' file for reference. Once the maintenance thingy is done I'm gonna give it a whirl. Thanks a lot for sharing!
