Bulk Rename Utility

Hi,

I don't know if I'm being blind or completely stupid, but is there anyway to customise the filter, so as to use non-specific terms.

I would ideally like to filter my results to only contain filenames with double digits.

Thank you.

The 12Filter only accepts:
Literal chars
* and ? wildcards
Space to separate multiple matches
(! may precede a match to negate it)
