You have to create SMT pad & use it.
In case your wizard not able to create SMT component, use nomal process of creating component normally & save it in library.
I follow same process for creating some components like Relays .
Lets say you want to conect SMA Panel Mount or surface mount connector. Like the one in attached figure, then simply find its footprint measurements from manufacturer datasheet and Make your own PCB Library, Goto Component wizard , Select DIP and place Vias and Pads. with distances according to footprint mentioned.
Then from your library, add the component into your schematics or PCB. A useful link for tutorial is here (https://www.youtube.com/watch?v=65hJw_dM5Jk)
