[enhancement]: Auto mode sync between stations. 
### Describe the solution you'd like

It would be great if enabling a security mode on one mode would enable the same mode on all stations.  Example: I use the keypad to set my system to “home” it would set all my station to home.   

I tried to set this up in HomeKit automations but the alarm system automations only have listener’s for arm, disarm, and trigger. Not changing modes.  

Thank you
