Editing Product Page Header Home/"product name"

Hello,

My website uses the store pages feature. I have multiple “product gallery” pages that bring the user to their respective individual product pages when they click on a thumbnail image in the product gallery. Once on the individual product page, there is a fixed header that comes as a part of the store pages feature. It reads Home/“Product Name”.

I am looking to:
Change Home to my Store Collection name (Bob Gruen in this case) and make sure it navigates back to the product gallery page.

I understand coding is involved and am looking for the code involved in doing so.
