How do you pass port number parameter data to Simulink Serial blocks

I have a need to be able to set the communication port number in my serial blocks prior to running the model (e.g. via a test harness or constant string block). The goal is to have the serial ports not "hard coded" in the model just in case Win 10 reassigns the USB device to another com port.
It seems like the "Port" parameter is limited to the drop down list. Does anyone know of a mechanism to allow for external Port setting?

As per my understanding, you would like to set the communication port number in your serial blocks dynamically. For this, I recommend you use the “set_param” function. To set communication port in the “Serial Configuration” block, please use the following command(use your port number instead of COM5)
set_param(gcb, "Port", "COM5");
I suggest you refer to the following documentation to know more about “set_param()” function:
The parameter name to be used in the “set_param()” function is “Port”. I suggest you refer to the following documentation for more reference:
I hope this helps you in setting the port number as an external parameter.
