Rename Copied files if Size or Date is different

Unless I am missing something, it would be awesome if Teracopy had a Rename Copied files if Size or Date is different button. I merge directories with many entries on a weekly basis and the ability to keep both files if the size and date (or both) are different would be terrific since two files can have the same name (example.jpg) but have different content. I don't want the Rename all copied files button because that causes files with duplicate content and wastes space.
