A way to execute some action on exported files

When I export JPEGs, sometimes there's a need to make some changes to them, such as:

• modify EXIF data based on something about the original files

• move the exported files somewhere where C1 can't export them

What I would like to do is create a C1 script that would trigger export with some recipe(s), receive the list of originals, and a list of exported files, and then do what I want to do.

Alternatively, it doesn't have to be a C1 script. As long as there's a way to invoke a command and pass it the info, it's all the same.
