Move a file to a drive and specific folder YYYYMM

Hi
I've just discovered this fantastic tool and bought the family pack for my home network based on reviews alone!
I've been storing my music that I download on a separate drive in a specific folder eg "/music/YEAR><MONTH>"
How do I automate this so that every download is stored in a different location based on this <YEAR><month> ie /music/201205/
Do I need to make the directory first or can Hazel create a directory if it does not exist based on some criteria?
It's not a show stopper, I'm sure I can work around this - but it would be great to be able to resolve this
Thanks
GD
