SABnzbd and Couchpotato?

Is there any way to install these on Dietpi. I have read the posts about them possibly being part of a future dietpi-software package but that appears to have gone quiet. I have tried using the instructions for installing on a Pi running raspbian buit it screws up Dietpi completely.
If there is a way can someone please explain how , I can’t find anything on this on the web.
