Is there a way to take one file in a multi-file document and upgrade it to a separate object with its own class?

Hi, 

Is there a way for a user that has a multi-file object to take one of the files and classify it as its own object in the database.   The reason that I am asking is to facilitate the task of users submitting attachments at once but then at another stage to take the files submitted and properly classify them.

Thanks in advance, 

Irene
