Intro
Every rock face in Rock Mapper has a unique FaceID (details here). Rock faces are automatically named based on the most recent rock face that's stored on the device (shown in first position on the Rock Face Gallery Page) if Auto Face ID is turned on. It will then use the same Level and Region values and automatically increment the Face Number.
Alternatively, the user can select Level and Region from a pick list or manually enter them.
Instructions
In order to change the name of a Rock Face (and the ZIP file plus all data stored within), tap on the title on the Mapping Page. You can then edit the Level, Region & Face Number. Face Number needs to be entered as type integer, Level and Region can be alphanumeric.
Alternatively, long press the thumbnail on the Rock Face Gallery Page and then choose Rename.
