Can one button move a point and change LEDs or relays?

Yes, that is one of the practical uses described for CMMME Prima.

Prima allows multiple outputs to respond to the same input. This means one button or DCC command can move a servo, switch a relay, and change an LED indicator at the same time.

This is useful for turnout control where the point movement, track polarity, and control panel indication need to stay in sync.
