Featured sub-Category?

I like the feature gallery ability. Question, what if I want to feature a sub-category instead? For example, I photographed a kart race last weekend. I have a sub-category under the category "Racing" for this. In that sub-category are five separate galleries, one for adults, one for kids, you get the idea. Would be convenient if I could feature the sub-category, make it easier for viewers to find.

The alternative is I make a new Category for the race. "Iron Rock Grand Opening". But then, as the season goes, I don't have all my kart racing under the "Racing" category.
