[Inkscape-user] Copying a few nodes from an object

Is it possible to copy nodes from an object with the 'Edit Node' tool and paste them?

I've tried copying just a few nodes from an object, hit copy, and then paste. Nothing happens.

Duplicating the whole object and altering the duplicate works fine, but it would save me some time if I can copy and paste nodes if it's possilble.

Any hints would be helpful! Thanks!
