edit nodes operation

this module is good at adding new nodes.
in some situation, our contentType's input fields will be growing up;
let's say , 2008-12 , contentType="movie" has field : title , body , field_link , field_author , you use csv to import only three fields data.
a years later , you have already changed some datas of these imported nodes , but you add a new field call "field_director", you also have a csv file mapping "movie-title" to "movie-director"
you just want to add the existing nodes the director information!

so , how to ?
