In a text field, such as the title, it is possible to add an automatic number to an asset sequence thanks to batch processing. This allows you, for example, to number the photos of the same report: Lighthouse 01, Lighthouse 02, Lighthouse 03...
You just have to select your assets, use the Batch processing option in the editing icon, check the Text field you want to edit, and finally choose Insert an incremental number.
You can choose the starting number, the increment (i.e. the gap between two numbers), and the number of digits composing the number.
