You probably already tried this, but doesn't work to put in a relative folder path in the output scenario ID dialog box, like you can with various support files like hotstarts and dsf0 files. If you really wanted to do it, you could probably use something third party - the easiest way I could think of would be to write an Autohotkey script to monitor the folder and move any PRF files based on the file name to a subfolder.
