I wrote something and was wondering if I could shorten it. I wrote:

sudo adduser pi audio 
sudo adduser pi video 
sudo adduser pi input 
sudo adduser pi dialout 
sudo adduser pi plugdev 
sudo adduser pi tty

And was thinking I could shorten it to:

sudo adduser pi{ audio video input dialout plugdev tty}

Would that work? If not how should I do it?
