Duplicate function wpcf7_maybe_add_random_dir to store files online in folders?

Hi,

I am trying to store uploaded files on my server by using CF7. Now at the moment i am able to sent the files by email and store the files in a folder (using wpcf7_upload_tmp_dir for this and altering file.php and submission.php by outcommenting @unlink)

Now i notice CF7 uses a random file name folder to store the file, my question could i use a CF7 input field value to create the folder name.

So folder would be {wpcf7_upload_tmp_dir}/username/image1.jpg

Maybe copying or hooking function wpcf7_maybe_add_random_dir ?

Any tips?
