Add a new messaging trigger, for as soon a tag is added or deleted from a booking. My use case scenario is this: when a guest confirms and pays for extra services (e.g. pool heating, when renting a crib-stroller-bbw grill, when requesting a complimentary early check-in or late check-out, etc; all this is done thru specific mini web portals that the guest accesses), certain tag(s) are added to OR via an API call by my property management software; I currently also have to add a note (via API, too), to make the trigger work, so a specific message template is sent to the guest.
