All files displayed in "Uploaded Files" list

[tsn]

Thanks for a very good file upload system!
Though, I have an issue ...

1. This is what I want the most:
In frontend I'd like the files uploaded by members of a Joomla! user group others to be listed in the "Uploaded Files" list for all members of this group, or for all users. How can I solve this?

2. The temporary alternative:
Setting a default owner of uploaded files in to a category.

Thanks!
