spline question

i have a question about splines,
i have a character with movement and when i click a location, it moves to the location.

is it possible to create a predetermined spline path for the character to follow when it is turning?

to make it gradually turn like a quarter of a circle rather than turning right/left sharply…

lets say, i have a spline turn left, spline turn right, so when the character knows it is about to turn right, it creates a spline in front of it to follow… then destroy the spline path when it finishes the path.

a better sample would be like the movement of a jet. when a jet has a destination to go to, it cant turn sharply immediately, it turns towards it’s destination slowly…
