Can I change the default attributes of a BICC extraxt file stored in UCM?

Summary:

I'm creating 2 extracts of BICC sourced from the same PVO for 2 different purposes, this is creating files with the same name. 

I need to download the files and store them in different folders according to the purpose, to acomplish this I need to identify each extract, however

I can't base on the manifest file because the tool used to download the files, can't read file content only look for file attribute tags.

Is it possible to update some of the file attributes when the extract file is created in BICC? Maybe changing the author or add a comment will help
