Collision Rule - PATTERN option

Have looked for guidance in the documentation, and can't see it...

Would like to have a pattern on the collision rule "New Name" option so end result is

~~<title> <incrementing number>

TILDE TILDE title SPACE 001

so for example, two copies of "FreeMovie" will show as
~~Free Movie 001 and
~~Free Movie 002

so that, all potential duplicates will appear at the start of a filename sorted explorer window, for manual weeding (and yes, manual subsequent rename)

Any guidance happily accepted
