Deep link into KC bot categories from an engagement custom button

Currently using a engagement (guide) Custom Button there are action types to open a specific KC Bot or Article. However our KC Bot content is broken down into Categories and when we refresh the content, we go one category at a time. We announce a refresh of a category to users with a custom engagement that opens the KC bot with a custom button. However we would like the button to take the user straight into the updated category, rather than the user having to remember which category has been updated from the previously showing engagements, scroll through and find it themselves, and click on it themselves.
