watermarking during batch output?

[Martin5000]

Instead of using something like zText to add a small text block to an image is there a way to do the same thing to any image as it is output via the Batch Output process? That way I could add different text depending who will receive them. I looked at creating a new set of Batch Export Settings but the none of the Settings appears to lend itself to adding some text like (c) or my name or something else.
