Is there a way to make your computer see the headset in the audio jack as separate from the built in speakers? I'm using windows 10?

So far, not yet because the jacks all look the same so unless some weirdo devices a way to implant a chip at the tip of that 3.5mm jack then maybe, in the future. Just wait and see. In the meantime, your next best bet is Bluetooth headsets and speakers.

Down the bottom right, right click O the speakers icon, select playback devices.
