How to get a second branch to deploys as branch.app.mydomain.net

The app deploys to moonlit-pika-8212cf

I purchased a domain via netlify (baliset.net), and deployed to linn.baliset.net 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 dev.linn.baliset.net or dev-linn.baliset.net. 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?

hi @tesilab :wave:t6: welcome to the forums and thank you so much for reaching out! Can you give this docs page a read as it has instruction for setting up branches.
