How to get a second branch to deploys as

The app deploys to moonlit-pika-8212cf

I purchased a domain via netlify (, and deployed to The DNS, SSL, all great.
I enabled additonal branches for deployment manually, rather than specify as a separate app.
I would like the dev branch to go to something like or I read on this site there was automated support for the first–but perhaps it doesn’t work because my main deploy is already to a subdomain? How can I get this to work?
