That is still 1 Title to Calibre (and it will probably run int Filesystem path length Limits)
I made a field SubTitle and strip the Calibre title down: No Series name in the title, No subtitle and I toss 'A Novel', things get lots more reasonable (lengthwise)
Code:
New Title "Harlequin Intrigue December 2014 - 2 of 2"
Subtitle "Kidnapping in Kendall County & Christmas Justice & Eagle's Last Stand."
No series:

You can use Home and End to get to the ends. Ctrl-arrow keys to jump words
All that is standard keyboard stuff
