WooCommerce Simple Code Fix?

Hi. I’m working on a WooCommerce site for our museum that is basically a catalog experience with a limited shopping cart. I’ve got many items in the catalog and I’m using the WooCommerce plugin to allow several ways to sort “products” in a sidebar widget. What I’m looking to do is just change the word “category” under the category filter. I want to change the word to “artist” as in “select an artist” rather than “select a category”

I’m thinking this simple fix must be in a PHP file somewhere in the WooCommerce plugin folders, either in the Single Product or Category Archive or something similar. I have done a pretty exhaustive search for this and haven’t found any fixes.

Anyone got an idea?
