Bulk update or rescheduling for multiple appointments if a resource is unavailable

Purpose

1.1. Enable automatic bulk rescheduling or cancellation of property appraisal appointments when an appraiser (resource) becomes unavailable, ensuring all stakeholders are promptly notified and calendar systems update in real-time.
1.2. Remove manual intervention, eliminating scheduling errors, and preserving service integrity by swiftly reallocating or rescheduling appointments en masse across platforms.
1.3. Support seamless coordination across schedulers, appraisal firms, realtors, clients, and third-party services for high appointment throughput environments.
