One-click option to duplicate items & folders

It’d be a big time saver if we could duplicate an item or folder, in place, with just one click.

At the moment in order to do so (correct me if I’m wrong) I can only copy selections while moving them (by clicking on the plus button), I have to memorize how far I moved them and drag them back where they were.

Suggestion images attached.

Thanks for your time
