Add a new broker, enter username and password, don't deploy and dont refresh. Export the new node - you will see the correct format.

If you wanted to do it remotely you could have an http endpoint or another mqtt topic. You could then set the mqtt node using dynamic subscription settings. Read the help text in the sidebar, it will give you the properties you can set.
