there's a 3rd party alternative route
grab a shareware utility that can capture & print-to-file a copy of folder+subfolder contents ( as seen in windows explorer) . I use printfolderpro
run that against calibre library then play with the settings & sort options until it's a decent list
then paste the output into a word or excel or whatever & do the final tweaks
if you only have one format per book this get you close, quickly
