I don't think the application is designed for this type db architecture. If you wanted to try this you would probably need to modify the tablename_templateTV.html & tablename_templateTV.html files.
Then you would need to modify the tablename_dml.php file to create a new function. It would probably be best to store uploads in an array for displaying in the table view include a file count function and include some error checking for duplicate filenames users may try, filetypes, filesizes etc..
