Multiple input devices in dom0

I have installed QubesOS on a Framework 12 (i5-1334U), and it is working quite nicely (I should do an HCL report, I know…).
However there is a somewhat annoying issue I found. The stylus and touchscreen are connected via I2C, and dom0 can use them with no problems. However, VMs see a single virtual input device that has the events from all the real input devices. That means than when using a note-taking application, I cannot distinguish between the touchscreen and the stylus so palm-detection does not work, and writing gets complicated (it is hard to write without touching the screen).

I haven’t seen anything about passing more than one input device to a VM in my searches, but I wonder if anyone has ever ran into an issue like this and found a solution/workaround.

Thanks!
