Hi,
There actually is a way to sort games.
First, you create Collections. Then, you add your game(s) to the collections.
Once you've got your organized Collections done, you then navigate to your Creator Page, click Edit Theme, remove your list of games from the Theme menu, then select to display the specific Collections, which will then show your games in a more organized way.
I did this for my Creator page. It takes a little work, but it can be worth it (in my opinion).
Edit: This is for making the games visible to the public. If you mean internally, like when you edit your projects... I'm not sure what to do there.
