cubic polynomial and B-Spline methods using the polynomial trajectory block in matlab simulink?

Is it possible to combine its cubic polynomial and B-Spline methods using the polynomial trajectory block in matlab simulink?

I am making a manipulator to describe and draw numbers. Cubic polynomial can create a straight trajectory, for example, the number 1 can be drawn. B-spline can create a flexible trajectory. for example, the number 0 can be drawn. Now, to draw the number 2, it is necessary to create a flexible trajectory and a straight trajectory and combine the above methods.

any suggestion to move it ?

Thanks in advance.
