How do I give two inputs to the transfer function block in Simulink?

In my simulation, I am trying to generate an output with two control inputs for the transfer function block. But the block allows only 1 input. Is there a way I can provide 2 inputs to it without having to give it separately?

By using Mux and discretizing the continuous transfer function from Analysis->Control Design->Model Discretizer in Simulink menu, you can do it. See the attached model for the usage.

Could you please explain it clearly ??

If you have opened up the model, you will see that Mux is an element that helps to create a nx1 vector from the inputs it has. In this case, since it has 2 inputs, the output of Mux is a 2x1 vector. Then, that signal goes into DISCRETIZED TRANSFER FUNCTION, NOT CONTINUOUS, and calculates the output for two different step input. This is the case.
