Messaging Rule Condition for Signed Rental Agreements

Problem: Currently, there is no way to trigger a message based on whether a guest has signed a rental agreement. This makes it impossible to automatically send specific information (like access codes for optional amenities) only to guests who have completed their agreement.

Current Workaround: Hosts must either send the code to all guests (including those who didn't sign) or manually track signatures and send the code individually.

Impact: This creates additional manual work for hosts and reduces the security/control over optional amenities.

Proposed Solution: Add a new condition to messaging rules that checks if a rental agreement has been signed.

Unlock: Hosts will be able to automate the delivery of amenity codes or specific instructions only after a guest has legally agreed to the terms.
