Metadata when adding books

[dc696969]

When adding books, Calibre can determine metadata either from the book itself or from the filename.

Most of my imports have fairly well structured filenames such that I can use a regular expression to enable calibre to determine author, tiltle and, possibly, series from the filename. However, in quite few cases we have the title only - which results in an author of 'Unklnown'.

May I suggest an enhancement to the Add book process such that when the use of a regular expression results in an unknown author, then Calibre shoud go to the book to get the author. This hybrid method should be in addition to the existing processes.
Thanks
