Show specific product subcategories instead?

I think this plug-in is a great addition to woocommerce.

How do I display the subcategories of a category instead?

It is common to have a main category eg: Author, Artist, Toolboxes
And Subcategories: Author -> Ben, Mike, Julie
Artists -> Kylie, Tammy, Tom
Toolboxes -> Metal box, 3 layered-box, Anti-rust box

How do I toggle it or, alter the script so that the product archive will display the subcategory of that particular category.
Eg: Type: Anti-rust box, 3 layered-box
or Authored by: Mike
or Created by: Kylie, Tammy

Instead of just showing the main categories which usually is too general, or usually a product can be of various category say for a song. This is what shows up when I enable the product category:

Artists, Kylie, Tammy, Producer, John, Music Company, Warner, Genre, Pop, Instrumental, Country, Australia, Year, 1993, Instruments, Digeridoo, Flute, Keyboard.

It looks messy and and the list is just far too many. I would rather like the ability to pick a main category eg: Artist. And then it will just show only the name of the artists which is within the category of Artists, eg: Tammy, Mike.

A nice short click able list. And I can use alter the code a bit on the echo codes by add By: or Genre: etc.
