Big impossible feature request

Might not even be an iosender thing or a grblhal thing, but I was thinking would it be possible to be able to hook up a 4th rotary axis as it's own stand alone device instead of needing a controller with another available axis? Either linking it with grblhal wit uart or i2c, or having iosender connect to 2 serial devices to control the rotary axis independently. Might be a huge under taking, but would be worth it to me to just be able to plug in the stand alone rotary axis.

With synchronized motion? Forget it, even if you paid me I would not do that.
A 4+ axis controller is not expensive, cheapest is around USD 15...

That's fair, was just an idea, mostly because I have everything I would need to build it laying around without needing to spend money and re-build my controller box with a new board.
