When are we going to be able to add our games to the Game Status list?

I play AssaultCube and various other older games, and these are not supported for no obvious reason. But according to the drop down list when clicking "add" I can share when I'm using Chrome, Calculator, Microsoft Store, etc. Makes no sense at all. Please allow us to manually add games since most of the games I play don't show up (but can your PC run Microsoft Calculator? Mine is a beast so it can!). Not submitting this as a request but more as a bug, since this makes so little sense and there are reports from a few years ago of this feature actually detecting games properly.
