1: Load the files into the List

2: Re-order in ascending order (click on Filename header as necessary)

3: Set Name collision rule = "Append number", Separator = "-"

4: Remove pattern method
- Pattern: "-.*"
- Use regular expressions:"√

5: Start batch

6: In "Progress" dialogue: Add files = "All items"

7: Renumber method
- Number position = 2
- Change to = "Relative to existing number"
- Number difference = -1

8: Start batch

Notes:
- 1: Collision rule appended numbers start from 001 not 000
- 2: Two passes are required because the collision rule is applied after all methods have been processed, so the appended number is not accessible until the first batch has been executed
