Universal Splitscreen option for games with lan

[XiGlove]

How would this work?:
Basically steam client could add option to launch 2 games at the same time with both games having half the aspect ratio so it could fit 2 gameplay into one

Why:
I think adding universal splitscreen feature for games like Borderlands 2 would be cool (especially they have splitscreen on console but not PC)

I am aware of the fact that a app called "Universal Split Screen" already let you do that, but every time I need to use it I need to get up from my couch and go to my PC and manually set those things up

I wish I could just have a button on the steam big picture mode and by using that button it runs multiple games the way i mentioned

it just makes sense with the rise of console-like PC or custom built steam machine or just using a PC like a console in general while having the steam big picture mode to simulate the console experience

And I'm sure Valve would consider my suggestion if it gets noticed because for the past years they have been adding more features to make PC and Steam Deck more "console like"

Tell me what you think about it
