This may be obvious, but I'm having difficulty figuring out how to set up an ExifTool Command Processor preset as a favorite. I know I can create a shell script ExifTool command as a favorite (as in the Help example for running a command line application: https://www.photools.com/help/imatch/#fav_basics.htm?dl=h-24), but I wondered if there's a more direct way to create an ECP preset favorite.
There are no dedicated Favorites for ECP presets. ECP is not something one usually needs regularly.
