Defaulting Product Filter for Knowledge Articles

Content

In 19B, Oracle released a few new filters under the "My Knowledge" transaction page (under the Help Desk module). These include Product, Content Type, and Category, and Locale (previously a filter). My client is wondering if the Product field can be defaulted, similar to how Locale defaults, from Manage Knowledge Locales task. 

Since there is no way to create a groovy script for this in app composer, as the page/object is not extensible, does anyone know of a way to default any of these new filter fields?
