Steam Runner Set OS

Please add a setting within the Steam Runner to choose what the OS of the game is. Most of my Steam game are windows games and I would like to set them to be Windows but the runner organises all of my Stream runner games as Linux games.

I like to use Steam Play/Proton within Steam and not the Wine Steam runner. I like the Steam runner since all you need to do to launch the game within Steam is provide the Steam Game ID.

With the Dolphin runner, in the Configure->Game options tab you can choose weather the game is a Gamecube game or a Wii game. I think the Steam runner should have an option in the Configure->Game options tab to choose weather the game is a Linux game or a Windows game.
