How to assign macOS dock to a specific/all screens

I'm running Sonoma 14.4 and have 3 external hi-res monitors. This is working great except I'd really like for the dock to appear on a specific screen -- which is not the designated "primary" screen.

Alternately I'd like to have the dock appear on all screens.

Is there an "Assign Dock to Screen #" setting hiding somewhere in Sys Settings? Or a dwrite command? Or sysctl? Or...?

Thx!
