Campaign Codex allows for custom map markers to be generated when placing journals on a map. Any Campaign Codex sheet with a name that starts with the pattern of [Optional A-Z][1-3 Digits][Optional A-Z] followed by a space, – or : will create a custom map pin with that pattern.
Examples of valid patterns:
- 1, 12, 123
- A1, A12, A123
- 1A, 12A, 123A
- A1B, A12B, A123B
The map markers are dynamic and will adjust when sheets are renamed.
The GREP pattern that is used:
/^([a-zA-Z]?\d{1,3}[a-zA-Z]?)
