@CRussel:
No need to recreate the wheel and/or do manually what can already be automated. The following tool does everything you have requested plus a lot more. It also does not do what you do not want unless you specifically tell it to, such as copying your audio files to the Calibre directory structure.
The Original Post clearly explains its flexibility.
Among other things, it will automatically create a custom Identifier to the original path if you tell it to via Dynamic Variables.
