Is there any reason why you can't use either "All Fields" or just "Sub-Category" for your action.
Since products are collapsed, they are not able to be passed through an action filter. Since each product is associated with a sub-category you should achieve the same results.
Hope that helps!
Hi Travis and thank you for your quick reply.
I quickly created a new field from subcategory (Addons) to demonstrate my point, so I cannot use sub-category for my filter. I was hoping there would be a work around for not having to expand the hierarchy in order for filtering to work.
