How do I add a new context menu item for peazip in its settings?

To give a better understanding of what I'm after please see the image, where I want to add 2 options for 1 Zip to .7z and delete files and 2 Extract and delete archive...

Is the ability natively there for its own context item or in the send to.. context menu also?

I've searched through the settings and the help file on the website and I came up with nothing.
