Subfolders and ShoveBox

When I download an Archive containing a folder containing music files I would like Hazel to notice that a new folder has been created containing music files, import these files into iTunes and delete the folder which contained them. Since the name of the folder containing the files will vary I'm not sure how to do this.
I've managed to do the above part in italics, but I want the Apply Rules to Subfolder to only apply to certain rules. Is this possible? i.e. Although I want to sort music using the subfolder rule, I don't want the Date Sorting rule (which puts files into folders named by date, for example 2008-12) to run since this will create an endless group of folders within one another.
I would also like to know if its possible to import text files into ShoveBox when they are created? Or would I need a script to run in order to achieve this?
Thanks very much for your help
