Is it possible to add the mqtt connect infos via a user interface page instead of the setup in the flow?  
I do similar things with tcp-connections, where msg.port and msg.ip are good friends of mine.

No, not possible but you can use environment variables e.g. ${brokerip}. So a kinda workaround can be achieved.

Notee. Env vars are only read on startup of node-red.
