Not parent, but I use a trackball. Apparently adding a plain scroll wheel onto one is rocket science or something, based on the prices.

There’s also the slightly smaller Deft Pro (https://switchandclick.com/elecom-deft-pro-review/) which I also own and use for travel — it has a superior scroll wheel and therefore may be a superior choice for you.
For me the Huge has a perfect form factor that outweighs all else.
On mac I use steermouse to map the buttons.
I promise to stop being a trackball pusher now.
