Buzzer Questions

I just fitted a buzzer to my matek h743 slim. Im getting various beep combos now.

Question 1. Is there a complete list of tones and their meanings - this here does not seem a full list Buzzer (aka Tone Alarm) — Plane documentation

Question 2. Im out of channels so have no switches left for turning on the lost model buzzer with a switch - what other ways can it be activated. OR is there a way to mirror a RCinput to another channel - im ok for instance with a single switch both turning on emergency motor disable and activating the lost model mode at the same time but there doesn’t seem to be a way to do this ???

Any help appreciated.
