Allow copying of just one file?

Hi!

Thank you for this plugin :)

I was wondering if there is some way to copy just one file, instead of a directory?

Usecase: i have /feed.xml that is being generated, but i'd like to copy that into /feed/index.xml. If I add a task, it'll create /feed/index.xml/feed.xml, which is not what I'd want.

Kind regards
