How To Add 'Copy as Path' to Opus context menu?

As the title says, I'm searching for a way to add the ability to copy a files' complete path via the right click context menu within Opus. It's a great time-saving feature to have available. Within Windows File Explorer, you just have to navigate to your file, then perform a Shift + Right Click to bring up the context menu that includes the 'Copy as Path' choice, click that option, and the path of the selected file is copied to the clipboard.

                                                                                      [url=http://imagehosting.biz/image/wUw][img]http://imagehosting.biz/images/2015/10/06/CopyAsPath.png[/img][/url]

Is this something that can be added to the right click context menu of a lister within Opus?

Or, if it's not possible using the context menu, would it be possible to make a button to do that function, and if yes, what would the coding be?

TIA !
