Scalable Multi-Level Listing Relationships (Grandparent/Parent/Child and Beyond)

Currently, Hospitable supports parent/child listing relationships. However, some properties have complex, multi-level structures (e.g., a whole property containing multiple townhouses, each with its own attached smaller unit). This results in numerous booking combinations (e.g., individual units, townhouses with units, or the entire property).

When a booking occurs at any level, the user must manually block dates for all related listings, which is time-consuming and increases the risk of double-bookings. The request is for a scalable listing hierarchy (beyond a fixed number of levels) so that bookings automatically trigger blocks across all related listings regardless of the complexity of the property structure.
