Feature Suggestion: More Flexible Pair Matching for Files with Name Variants (e.g., Language Codes)

Hi,

I usually use the "Pair Renaming" feature in conjunction with ExifTool tags like <ExifTool:Duration> to consistently apply metadata, such as video duration, to a video file and its associated subtitle files.

My common file structure looks like this:

MyVideo.mkv
MyVideo.en.vtt
MyVideo.de.vtt
MyVideo.fr.vtt

The current issue is that the "Pair Renaming" feature does not recognize the subtitle files (*.lang.vtt) as a pair with the video file (*.mkv) because their names do not match exactly due to the language codes (.en, .de, .fr) preceding the final .vtt extension. This prevents easily transferring tags like duration to all related files in one step.

Would it be possible to introduce an option for "Pair Renaming" that allows for more flexible pair matching? Ideally, a setting could allow users to specify that parts of the filename before the final extension (such as .en, .de, or other separators like _de) should be ignored during the matching process. An alternative approach could be to limit the matching to the part of the filename up to the second-to-last dot.

This enhancement would significantly simplify applying metadata to sets of files that follow such common naming patterns.

Thank you!
