Situation
Leases, insurance, safety certificates and service contracts across several buildings, each with its own notice rules.
Examples
Property managers
How the register is set up
Items are tagged by building in the title and notes; break-clause notice periods are recorded in calendar months so the deadline uses month arithmetic.
What changes day to day
Break windows and certificate expiries appear on the same 30/60/90/180-day view instead of separate spreadsheets per site.
Limitations
There is no per-building hierarchy in this stage—buildings are recorded as tags, not as a separate structure.
Illustrative example. Not a real customer or contract.
