It's absolutely possible! Basically, you can set your system to start on any view by selecting the desired startup view in the settings of Big Box. However, it also depends on how your folder structure is organized! Some people prefer to launch by system category, while others go with playlists. I believe you can also start directly with your platforms, and more recently, there's the option to use the new discovery/trending menus.
So, there are quite a few choices! 😆 But if I understand correctly, based on your screenshots, and assuming you’ve chosen to launch by categories first (like I do), you can set which view you land on at startup. You’d just need to modify the "Platform Vertical 1" view, for example.
I can do it for you if you want—it would only take me about 3 minutes! That way, you can test it out.
