This is for property owners and their staff. Spaces live under Parking, then Spaces.
A lot first
Every space belongs to a lot — a garage, a deck, a surface lot. Add one under Lots and layout before you add spaces to it.
Adding a range
Add spaces asks for the first and the last, and fills in everything between: from A1 to A50 gives you fifty spaces named A1 through A50. It tells you what it worked out — "50 spaces, A1 through A50, nothing skipped" — before anything is created, and asks you which you meant when a range could be read two ways.
Paste a list instead takes the labels themselves, one per line or separated by commas, for a lot that was never numbered tidily.
While you are planning the range you can mark individual spaces as EV, accessible, reserved, or skip them altogether.
Afterwards
The same deck edits spaces in bulk: add or clear the EV, Accessible and Covered tags, or remove a selection.
Opening one space lets you set its tags, its notes, and its price — Charged with a rate of its own, or Free. A space with no rate of its own follows the property's price.
What it costs you
Parken Lot is priced per space per month, so adding spaces adds to what you pay and removing them reduces it. A space added part-way through a billing period is charged only for the rest of that period, in one invoice for the batch rather than one per space.
