Is the single thumb button on the left hand side programmable as a button to switch between sources 1, 2 & 3 a la the Triathlon mouse?

The Logitech MX Master 4 has a button on the left-hand side (in the thumb area) that can be individually programmed using Logi Options+ software (e.g. to control shortcuts, macros, actions, etc.). However, this button is not primarily intended for switching directly between devices (e.g. source 1 / 2 / 3), as is possible with some "triathlon" mice. In reviews, it is usually described as an "actions ring / menu button" or "thumb haptic button", which is used to open an overlay for functions.
