Right now the only way is to hide your games in the main section of your profile, and show them into categories below instead. Hope this helps!

Oops, typo. I meant collections. You can make collections and put any games in them, including your own. The Add to Collection button appears on mouse over on search results, and also in the upper right corner of the page when looking at any game's page. Then once you have a collection, you can make it public, and it will appear below your creator profile.
