How to display Subsystem Input Port Number in Simulink

Hi everyone,

In Simulink, is it possible to temporary display the port number of a subsystem? Something like this :

This could be very useful when you have a subsytem with many inputs and you want to track the port number associated.

Thanks!

SignalX,SignalY and SignalZ are always in asceding order (1,2,3,4...) and you can always track signals using highlight to source and highlight to destination using right click on the signal.

This might be close. Right click the Subsystem block, click "Signals & Ports"

Yes I know about this menu but I'm looking for something faster where I could hover my mouse over an input and it would display the number.

If really needed, you could write a script to auto generate the "Icon drawing commands" consist of "port_lable()" to mask the subsystem block.
