Is it possible to specify gear up and down transit times for each gear?  In real airplanes the gear never ( well rarely, maybe ) sequence in perfect unison.  In reviewing the xml files for the 737, I note there are transit times defined for each flap position, but the kinematics for the gear is only a single value for up or down based on gear selection state.

Is this something in Nasal?  or native code or something in JSBsim?
