• {day} - Current day in DD format

Configuration Options:

• Counter Start - Starting number for the counter (default: 1)
• Counter Padding - Number of digits with zero-padding (default: 3)
• Case Control - Convert filename to uppercase or lowercase
• Preview in Processing Chain - See filename patterns when configuring the rename step

Examples:

• {original_name}_{counter} → image_001.jpg, image_002.jpg
