Trait to improve insight bonuses?

Like Fate's Favored for Luck and Optimistic Gambler for Morale?

I've double checked a few sources and couldn't find anything. Its a pretty reasonable trait to create from scratch though. Maybe mention the idea on the Paizo forums? One of the devs might see the post and think to add it to a book.
