Custom action button

Hi, currently when uploading files, there are cancel and edit action, is there away to add custom action like download so that when click it will fire the event will file that can be reused again like download, or is there any event that fired when clicking on file icon because am read all the docs and not find something like that.
my propose of this, because sometimes i initialize by adding some files from server so that i want to add ability to end user to download files or add new files
Thank you
