A few questions before buying WP File Download - WordPress File Manager

Hello we are interesting of plugin "WP File Download - WordPress File Manager" and we have the following questions : we understand by the online documentation that we may provide an individual access of concrete user to file's content, but my question is : does it possible for us to correct shortcode via which we will integrate the module with file's content in user page to our Wordpress site?
2. Shall we do addition or edition of columns of "Table theme" in a way that we will be able to find files on the content that is at the columns via filters and Search engine. For example: we create a column called " Documents number " and in the Search engine to have a possibility to search a content on this column.
