Yes, but I think your concept of "output" is incorrect.
The filenames created by calibre for the files in its library are not changeable. They are for calibre's use and not your's.
The naming pattern of a true output file, one that has been exported from calibre via the Send to Device or Save to Disk functions, can be altered via the settings in their respective Preferences sections. Explore the Save Template portion of the Send to Device and Save to Disk sections.
