TE=Starson17;1084584]Sure. Change the author's last name to be all caps before you save.
I have saved the file to Calibre with the authors last name in caps. I have changed one files author's name via the meta edit option and neither of them save to disk with the last name in caps.
I have tried with & w/o the option to take metadata only from file. In each case, the last name is NOT in caps. I reverts to lowercase letters.
