Has anyone had luck making device specific touch control layouts? I've read the various guides and there doesn't seem be any way of having a touch layout unique per Steam Link app device that connects.

I've even saved the same layout twice to have a tablet & phone version, but the input locations seem to be universally shared across "touch controllers", even when the touch controllers have different names, aspect ratios, etc.... making tablet spread out wide or phone too tight/big if i accommodate one or the other.

Am I missing something?
