Add more vehicle for SITL in FlightGear?

I’m new in Ardupilot and learn to use in SITL before real use in drone, plane, car etc. I’ve success use fg_plane_view.sh (Plane) and g_quad_view.sh) (Copter) as description here
https://ardupilot.org/dev/docs/setting-up-sitl-on-linux.html.

Is there a way to add more than 2 of these script guideline? For example : helicopter , other kind of plane.

Well, I figure it out already just copy those sh script and change name of Flightgear aircraft.
