TinyUSB is tiny for a very good reason. It's very limited. On top of that the Pico doesn't have much RAM so it's restricted even more. Messing about with USB is decidedly non-trivial so doing things with it is very programming-intensive. I doubt very much if any extension to the Pico's USB capabilities will or even can be done.

It might be better to use a CMM2 for this. The PicoMite 2 is still very limited.
