Add ability to hide tenants from drop-down

In the Transactions area, when selecting a unit through the drop-down, the list shows both current and older tenants for each unit (see screenshot). The number of unneeded items in the list grows over time unless I delete the older leases from the system, which creates its own problems. A simple checkbox for each lease (in the Leases & Tenants area) to determine whether it shows up in the list would solve this. You can’t do it automatically based on the move-in date, since there are often related expenses after move-out.
