Automated Messaging Triggers for Upsell Purchases

The user is requesting the ability to automate guest messaging based on upsell purchases in two specific ways:

• Immediate Trigger: A messaging rule that triggers and sends a message immediately whenever a guest purchases an upsell item, including during an active reservation.
• Check-in Trigger: A messaging rule that allows a message to be sent automatically at the time of check-in, specifically targeted at guests who have purchased an upsell item.
