can i upload list of multiple f/r items?

I have to replace ~600 5 digit numbers on ~600 different pages with the same number of totally different 5 digit numbers. Can i use this plugin and upload my list in whatever format (csv, xml, whatever) and have it run through an replace all of them for me? If not, do you know of any find/replace plugins that can do that? or any other way to do that?
thanks very much, r
