You can make changes in the mydownloads section (front end/user) like, modify, broke DL, etc, etc, then it will show in the 'waiting block'.
I was looking in my admin and seems you can't edit direct from admin yet only:
Submitted DL <--- front end submitted.
Broken DL <--- front end submitted.
Modified DL <--- front end submitted.
Hope this is of help.
