When manually adding a game is there any way to add the OS of it? Currently my manually added PC games don't show up when I filter by 'Windows' for example. Is there any way I can mark these games as Windows so they show up under that filter correctly like my imported games from steam or uplay do?

I'd like to start adding various console games soon so it's going to get messy if I can't use the Windows filter for all my PC games.

Also on that note my imported game of Populous from Orgin is also not marked as 'Windows' for some reason. It's the only one that disappears from the Origin games when filtering by Windows. I also need a way to add Windows to that.

Thank you.
